PCMforless Introduction Special - $99 tuning!

[Kelly_PCMforless]

http://www.pcmforless.com/images/trailblazer.jpgHello TrailVoy enthusiasts!http://www.pcmforless.com/images/trailblazer.jpg



We are excited to announce that we are now offering tuning for I6 Trailblazers/Envoys (also Colorados & Canyons) at an introductory price of $99. We have been in the tuning business since what seems like the beginning of time - chances are you may have heard about us already if you know anyone with a modified GM. PCMforless has also been featured in GM High Tech in just about half their issues every year.

So why is it so cheap?

While we are well known within the f-body, corvette, and truck world, we now want folks to know that we are doing Trailblazers/Envoys as well. We feel like we have a great product to offer to you - and what better way to get it out there than to make it ridiculously affordable. And if you don't like it - we'll buy it back!

We have the ability to retune the trucks for all sorts of modifications - but this is something that someone with even a stock truck can benefit from. We love our 2005 Trailblazer, but it had too much of that "big honking truck" feeling to it...you know - it didn't feel like it wanted to get out of its own way, shifts took all day, gas mileage was sub par. After playing around with our truck, we really fell in love with it...and hope that you will too!

Here at PCMforless we can also provide a core computer, just in case your truck is a daily driver and you can't afford to be without it. The core charge is $99, and is 100% refunded when we receive your stock PCM. You are more than welcome to keep the PCM and not receive a refund, we just ask you to please notify us so that we know how many cores to expect back.

Before we tune any PCM, we start with the latest calibration straight from GM. This means any computer flashes or updates that may have been done by your dealership are taken care of with us. These can be little things like flashes for a more accurate gas gauge, or a rough idle. In any case, after the PCM is freshly reprogrammed, we build our tune off of that file.

What exactly am I getting for $99?

We are selling a complete tune for $99. We help put a little pep in your engine's step. We make the transmission feel more performance oriented. We can also remove speed limiters, change idle, change tire size, etc to accomodate for all of your modifications. With our personal TrailBlazer, we have noticed an additional and realistic 2-3mpg.

So what are my options for ordering?

1. You can send us your stock PCM up front. Fill out an ordersheet, make a payment, send in your PCM. When we receive the PCM we will tune it and send it back to you. Total cost, $99 + shipping ($15 priority, $30 express).

2. You can use one of our core computers. Fill out an ordersheet, make a payment. We will tune our core computer, send it to you. You install that computer, send us your stock computer (within 21 days). Total cost, $198 + shipping up front, and then $99 refund when we receive your PCM.


What else do I need to know?

1. Chances are you will need to do a VATS relearn. This is a simple procedure that will take 30 minutes. It requires no special tools and very little effort. PCMs come with full instructions on how to do this.

2. There is a very small chance that you may also get SES light to do a CASE relearn. A CASE relearn is simply a procedure for the computer to learn the manufacturing error in the crank case position sensor which is used for detecting misfires. It is a simple procedure that anyone with HPtuners or EFIlive can do (in person). It can also be done at your local dealership (though you would likely be charged around $50 for it).

What about Trailblazer SS?

We have the ability to do these as well, although they are not part of the group buy. For more information on SS's, email programmer@pcmforless.com

How do I place an order?

By phone, or on the internet. Feel free to call between 9am and 7pm eastern standard time, to either order or ask questions. My number is 704-307-4227.

If you want to do it on the internet, visit www.pcmforless.com. Under "ordersheet" you will click on the appropriate vehicle and enter in your information. After submitting the ordersheet, you will be redirected. If not, go to Prices & Ordering, click on your vehicle, and it will lead you to a paypal checkout.

I could sit here and tell you about our services until I am blue in the face - but here are some actual emails/posts from our prior customers, who either got tuned for a Trailblazer or a Colorado/Canyon:

-------------------------

"OK Guys, So I've been in communication with Alvin for several months now waiting for him to finish the I5 and I6 PCM tunes, and this weekend I got two PCM's from Alvin - one for my wife's '05 Trailblazer, and one for my '05 Colorado Xtreme.

The tune for the Trailblazer is SWEET ! You can feel that the car is not laboring as much anymore as soon as you get behind the wheel. The car runs quieter, shifts crisper, has better acceleration, and is just better all around - great job ! (But Alvin has a Trailbalzer too so I was not surprised!)

The tune on the Colorado was geared more towrd performance. Like the blazer, you can feel that the truck is not laboring any more. The truck revs higher now before it changes gears and the shifts are crisp - you can feel them snap into place - no more lag. The car takes much less gas pedal to go the same speed now - and the increase in acceleration was very nice. I got on a straight away doing about 20 - pushed the pedal way down - but not WOT - the truck accelerated nicely until it hit about 4500 rpm, then my AEM started to growl, and I felt like I was being shot out of a cannon. The truck quickly went up to just below redline before it snapped into the next gear I was doing about 75 - and I had a big grin on my face. I'm running half and half right now - 87 and 89 octane - and I hope to see a little better performance yet once I start running straight 89.

Great job Alvin - I am a happy customer ! "

--------------------------

"The truck runs much smoother, it has pickup it never had before, and it doesn't labor any more like it used to. The shifts are firm, but not annoying, and I noticed this morning on the way into work that once I get into the upper gears (auto transmission) I barely have to touch my foot on the gas pedal in order to maintain a speed of 60 mph now. It just keeps getting better! "

--------------------------
"I ordered my PCM from Alvin last Thursday, and had it at my door the following Monday. Much to my happiness, it was an entire computer, not a chip or daughterboard to replace.

Even though the instructions are strainght forward, I managed to mess it up. i posted a PM to Alvin at 10:00pm last night (pacific), and he got back to me within an hour!!! I couldnt believe it.

I was getting the dreaded case relearn issue, and the vehicle wouldnt start. Turned out I wasnt trying to start the vehicle each "cycle", so I didnt actually complete the process per his instructions.

Once I did, it fired right up. From the start, I have restored computer function. I have had 2 reflaches from the dealer based on computer-related issues. This seems to have cured those problems, so even with no performance improvenments that would be worth the price.

I havent driven it much yet, but the improvement is noticable. It wont roast the tires, but it pulls harder from the light, and the "quickened" shift points are great...not jarring or anything impractical for a daily driver.

I plan to get it out on the highway this holiday weekend, so I'll post again. So far I am EXTREMELY impressed with PCMforless and my purchase."

------------------------------

"I installed mine on Saturday and I noticed a difference in the truck right away! It is much more fun to drive now. I got about a half a tank of gas on th new PCM and it seems to have improved my gas mileage, but I won't know for sure until I fill it up. The truck feels lighter because of the tune, it doesn't take as much pedal to get it to move. I am very happy with my experience with PCMforless!"

------------------------------
"I ordered my PCM Friday and got it in today. Install was easy and only took a few minutes. The security relearn took the longest, but was still only about ~40 minutes with me giving it extra time to sit.

The truck idles smoother, and seems to rev quicker. Sitting at a stoplight now the truck doesn't have that slight vibration like it used to, with the quiet stock exhaust on it I can hardly tell it's running. There is a definite improvement in acceleration from a standing start, it actually puts you back in the seat now instead of the slow roll into the throttle feeling it had before. Shifts are quick, I can tell the difference under part throttle and WOT. The part throttle shifts aren't annoying, they're just a little firmer/quicker and are just right IMO. Under WOT with the Jet Servo and the new PCM the shifts are great, it's not hard enough to make me feel like I'm going to break something but it's very quick and firm, it makes me hate having an automatic a lot less. Laughing Acceleration through the RPM range feels stronger and a lot more linear. Instead of the big lunge in power in the upper RPM's it's a strong and steady pull, a big improvement. Part throttle has a nice improvement as well, it downshifts the way it should now at highway speed instead of trying to lug around in OD and as others have said it doesn't take as much pedal to get it up to speed."

This also applies to the 2002 I6?

Yes, All I6!

[ScarabEpic22]

What do you use as a tuning program, if I bought a tune could you just email it to me? I have EFILive.

[brochad]

I am somewhat interested... Just wondering if this is a deal or not, seems like the same price you are offering on your website to the "public," or did I miss something?

[Kelly_PCMforless]

If you ask me $99 is a pretty good deal if you are shopping around :yes:

I listed that price on the website because 99.9% of people who are looking at that page are going to be coming from this website. We don't advertise Trailblazer stuff anywhere else, so to make things easier, the price you see in this thread is the same as the site. In a few months it will most likely be priced like our other similar PCM's.

[Kelly_PCMforless]

What do you use as a tuning program, if I bought a tune could you just email it to me? I have EFILive.

Sure we can do that, same $99 price. Shoot me an email if you are interested (kelly@pcmforless.com) and I will walk you through a custom payment so that you don't get charged for shipping. :)

[AlvinPCMforless]

Hi Guys,

It looks like Kelly has made a good introduction for us. I just want to let you guys know that we would like to the best job possible for you guys. If you get a program from us and your less than thrilled or impressed let us know. We will either go back and re-adjust the tune for free or buy it back from you.

If you have any questions shoot us a email or call us. We are around the phones from 10-7pm M-F. We also offer full chasis dyno tuning here in the Charlotte NC area.


Thanks
Alvin.

what would be the hp gain on a i6?

[Kelly_PCMforless]

what would be the hp gain on a i6?

We typically see 10-14 hp. We hear the seat of the pants gain feels great :D and of course the rest of the tune makes the truck feel so much better as a whole.

[blktbon20s]

sometime 10-15 hp isn't noticeable but w/ our tune is it slightly noticeable? or is it more for the mhp?

[FattyTBEXT]

We typically see 10-14 hp. We hear the seat of the pants gain feels great :D and of course the rest of the tune makes the truck feel so much better as a whole.

Sounds like a great deal to me. Normally the changed shift firmness, shift points, and reduced torque management are worth well over $99 alone.

Is it 10-14 hp across the whole dyno graph or is that peak? The Westers had a peak increase of 38 hp on 93 octane, but that's not the average across the graph.

[ScarabEpic22]

Awesome, I will definately talk to you guys, maybe even today for a tune. Im leaving on a trip tomorrow night and would love to have the ability to switch tunes on the fly via EFILive.

Also, do you guys do difference octane tunes as well, like a 93, 91, 89, 87 and then some combos of each like 91/87 dual fuel? If so, that would be awesome.

[AlvinPCMforless]

You will definately notice a very nice improvement to driveablity.. Like I said earlier if your are not impressed let us know and we will do more for the tune or buy it back from you. The difference we make to the I5's is something that you feel just in every day driving not just flooring it around.

We are tuning things to make a definate and positive improvement to the part throttle driveablity. Which means the truck will go with less accelerator pedal. You will definately notice the difference. We also do alot of transmission tuning beyond just shift firmness to keep the car in the torque band longer during periods like pulling out in traffic.

Sounds like a great deal to me. Normally the changed shift firmness, shift points, and reduced torque management are worth well over $99 alone.

Is it 10-14 hp across the whole dyno graph or is that peak? The Westers had a peak increase of 38 hp on 93 octane, but that's not the average across the graph.

Its a full out tune including different timing and fuel tables. We are just trying to make everything affordable for eveyrone and make these I6's drive like they actually have the 27x-28Xhp that they advertise.

The last one we did picked up quite a bit especially where the AFR dove at the end (22rwhp on 89)but I like to tell everyone the conservative estimate as a no BS this is what you get type of deal.

Absolutely. We are using HPtuners but I'm also a full workshop in EFIlive which is an awesome tuning software/solution.. SO I can build you a file and suck it down with EFIlive so its in the apporpiate format.

[lilchoke]

sounds pretty good. i missed the july special. is this a limited time thing???

[ScarabEpic22]

Awesome, I need to have the dealer reflash my PCM anyway with the new cals, so for I will get a tune!

Thinking a 91/87 one, I will talk to you later today about it.

[Bulldog]

Where are you located in Charlotte?

[VTODD]

i have used several different pcmforless tunes in the past with several different vehicles. every tune was GREAT! my brothers silverado is running a pcm4less tune right now, and hes still grinning.

is bryan still at pcm4less?

todd

[Kelly_PCMforless]

We will be doing this for at least another month or so, and then decide where to go from there :)

Where are you located in Charlotte?

East Charlotte. Around the area where East Harris meets Hickory Grove rd, if you are familiar with it.

Yes he sure is. Bryan is located in PA and does mail order for 94 & up cars/trucks. We are located in NC and do mail order for 93 & older cars/trucks, colorados, and trailblazers (and lots of random things on the dyno).

[ScarabEpic22]

Email sent!

Hoping for a 91/87 dual fuel with better shifts, reduce TQ management, and upped limiter (hopefully, EFI I dont think can do it yet).

[Black Ice]

Hoping for a 87 fuel tune with better shifts, reduce TQ management, and better gas mileage. can u make that happen for a stock 03 TB?.

Hey Erik, I just got your email (2am). We have been out dyno tuning since 9am Saturday, so I was not around the computer to email you a file - sorry about that. I will be sending you an email shortly with more information.

Certainly!! I think you'd love what we can do for you. :)

[ScarabEpic22]

Well, I ordered my tune from PCMForLess today at about 3pm PST. Cant wait to get it and put it in my TB!!!

I asked for 2 on shift firmness (I have a shift kit as well), no limiter (if posssible), and a 87/91 dual octane tune (if not able, Im getting a 87 tune).

Hopefully Alvin can whip one up for me today or tomorrow and I can have it in my truck by tomorrow PM or Friday at the latest.


(BTW, they are sending me my tune via email for EFILive so I dont have to send in my PCM and not have my TB for a few days.)

[MyTBSS]

Ok so my other truck is a 05 Coloado I5....you do core exchange but do you have to have a crank relearn on it like I would on the TBSS? I am interested in getting this done on my Colorado. Also, can the dealer see your tune?

Thanks

We have a few different ways of doing the Colorados, since the CASE relearn is unavoidable.

1. Send in your PCM outright. We will tune it without updating the GM calibration file, so you will not need a CASE relearn. Downside, you have to be without the truck for a few days. Total cost, $114. We can help you out with overnight shipping if need be.

2. Core charge. We send you a tuned PCM, you will need a CASE relearn. Most people have been going to dealerships and having it done for $50 or so. It can be done by anyone with a Tech II. Total cost, $213, $99 refunded when we get your PCM back.

3. Loaner program. This is for people who can't be without their trucks, and don't want to do a CASE relearn. We send you a stock PCM for your VIN. You send us your PCM, which we tune, but don't do the GM update. You get that tuned PCM back & install it, no CASE relearn necessary, and then return our loaner PCM. Total cost - $269, $99 refunded when we get our PCM back.

The dealership can't see the tune.



(BTW, they are sending me my tune via email for EFILive so I dont have to send in my PCM and not have my TB for a few days.)

We emailed it out tonight (9/6). Let us know what you think.

[chaotic84]

I have an 02 Bravada with the 4.2, will this tune work for me?

[chester0001]

I have an 02 Bravada with the 4.2, will this tune work for me?

It is the same truck basically so i would say yes :)

[ScarabEpic22]

I have an 02 Bravada with the 4.2, will this tune work for me?

Yes, it will.


Update:
Flashed my truck with the tune, much smoother shifts than the other tune I had originally and still are smooth at 5200rpms (very impressive). Only thing I cant comment on is the towing difference and mileage between stock, my custom tune, and PCM4Less's tune.

[cswagner]

So you didn't see any difference towing then?:confused:

[Kelly_PCMforless]

So you didn't see any difference towing then?:confused:

I think he means he hasn't towed anything, nor ran through a full tank of gas yet.

[ScarabEpic22]

I think he means he hasn't towed anything, nor ran through a full tank of gas yet.

Exactly, I had no gas in the tank yesterday when I flashed the PCMforless tune to my PCM. I went and got a tank of 87 from Chevron and drove for only about 15mi between yesterday and today.

I was hoping to report on the towing differences this weekend when I was supposed to winterize my boats, but since Im sick I wont be going over this weekend.

Towing difference will have to wait until next spring man, sorry.

i want in on this buy... i would like to buy a core and have you program it.. how do i go about paying?? more info my email is ratmotor99@yahoo.com


i have a 05 tb ext 4.2 all stock, don't mind paying for 93 oct.

thanks and look forward to doing this

Read the initial post and goto their website (or call them, very nice people to deal with).

[chester0001]

Ok here it is guys,

I got my PCM4less yesterday.. And i must say im pretty happy with it.
I did however change a couple of things around, for some reason 5500 rpm max on 1rst gear didnt sound right to me, theres another minimum 500 rpm of power left so i put it at 6000 for all the gears.
And i will be tweeking it over the next couple of weeks, months, years
:D

:D

THANKS for the tip on that. I just opened up the box my stock PCM's in to ship them tomorrow and added that I want the upshifts at 6000, redline 6100, rev limit at 6200 like stock. I need it to upshift at 6K for my 3.42 gears, for max RPM into the next gear.

Like ScarabEpic22 said contact them directly. I have emailed and talked to Alvin on the phone.

[chester0001]

Ok,
I just went on the highway,
still have the speed limiter... AND for some reason up to 140 (approx) it performs well then its a dog to 170 then it dies..
I donno seems to me that i used to get 170km/h without realizing i was going that fast

Ill try to make a log this WE and send it to PCM4less :undecided

What octane tune did you get?

87/91 yeah i sent them an email asking a question yesterday and no news from them as of yet.

Wil keep you posted opn results and tests..

Your email got sent to my orders instead of my inbox, so I missed it. Occasionally that happens if you don't type in kelly@pcmforless.com or alvin@pcmforless.com.

I was just looking over the ordersheet and I don't see anything about removing the speed limiter.

I will let Alvin know about the emails/posts and he will get back with you tomorrow morning since he has been dyno tuning all day today.

Thanks,

Kelly

[ScarabEpic22]

I did some testing yesterday, with the 1-2 shift set at 5200rpm, it actually shifts at about 5900 rpm which with 3.73s is perfect, it puts me right in the sweet spot of the I6 powerband. Plus, no annoying lag for .5sec and then a slam into 2nd. I think the I6 was actually hitting the rev limiter, and a couple times I saw the rpm guage hit at least 6300rpm, possibly 6400epm. Not exactly the best thing to have happen, but post tune is perfect!

[AlvinPCMforless]

Hi guys,

Glad to see you guys are pretty happy with them so far.

I do make quite a few changes that seem a bit counter intuitive. One is retiming the WOT shift on the I6's. The reason why I do this is because I feel the factory shift is too late. Have you ever floor a stock TB, let it wind all the way out to 6100RPM then shift then all of a sudden you have this BIG surge in torque and your off again? That surge of torque you feel in the next gear up is because at 6000RPM in the previous gear you fell off the face of the earth as far as torque band goes. This is evident in the following dyno graph

http://www.pcmforless.com/images/dynosheets/trailblazer.jpg

Every tune that leaves here is custom for the customer. So if you feel better at 6100 RPM I can do that however my testing has shown to me that the trucks are better suited to shift earlier than that. The trucks stay in the torque longer giving better accelerator with the pedal to the metal.


If you guys get these PCM's and have any questions or issues give us a call or send us a email directly. I personally only make it over to this board when someone calls my attention to it. I'm also on the dyno most of the day but Kelly is here all day long answering phone calls and taking care of most of my emails so we are pretty easy to get in touch with. I would much rather you email questions/concerns directly to us so we can handle them quickly and effectively.

Alvin just let me know he did 20 dyno pulls on a LL8 (4.2L I6) TB yesterday trying to squeeze some more power out of it, I should be able to report gains when I get back in town on Sat and can reflash my tune with an updated one from him!!

Im pumped, and look at that dyno graph. See the absolute flattness of the TQ curve, stays above 200ft lbs the entire time. Absolutely CRAZY!!! And that my friends, is why the I6 pulls so hard all the time.:yes:

Hey Alvin,

Ive just cent an email to Kelly.

Dont get me wrong im really happy with the tune, i just like knowing i understand the why and the how, if 5500 rpm is where its best ill set it at that. Im pretty much a hands on guy, Im new to tuning but i love to learn those things. (you wouldnt want me living in your area. Trust me) id find any reason to hang out and learn :D thats pretty much how i learned my work skills..

I can see on the dyno chart that 5500 is pretty much max torq
but do you have a chart where its tuned? im curius to see the big difference.

Thanx agan
Charles

[tblazed]

I did some testing yesterday, with the 1-2 shift set at 5200rpm, it actually shifts at about 5900 rpm ....

How can it be programmed to shift at 5200, but not actually shift til 5900??? :confused:

[AlvinPCMforless]

.

That chart is a before/after tuning. The red run is tuned.. The blue run is stock. As you can see the truck has way more power under the curve and is much smoother

[AlvinPCMforless]

How can it be programmed to shift at 5200, but not actually shift til 5900??? :confused:

WOT shift points have to meet 2 qualifiers. MPH and speed. So if its programmed 5200RPM and 40MPH it won't start the shfit until both of those have been met

Yeah i noticed after i wrote.
Oh well i couldnt have looked dumber if i tried :p

WOT shift points have to meet 2 qualifiers. MPH and speed. So if its programmed 5200RPM and 40MPH it won't start the shfit until both of those have been met

Yep, thats why right there. If Im cruising at 20 and punch it, it will drop into 1st, pull past 5200rpms (but not 40mph) and then hit 40mph and shift.

Ordered by PCMforLess tune yesterday. Can't wait to get it installed.

Thanks Kelly and Alvin!

I am not sure I agree with short shifting to second gear. The engine torque does not fall off enough to be making less wheel torque than it would in the reduced rpm of second gear. Keep in mind that the transmission has a much greater torque multiplier in first gear than second.

Interesting, I might play around with the 2-3 shift point a little when I can actually get out an play at 75-90mph safely. Dont want to do it because there is a lot of traffic and its dangerous.

You should try it. I've played with it quite a bit and IMHO the factory shift on 1-2 is too delayed... which is obvious when you feel that surge of torque after the 1-2 shift is completed.

Alvin,
Is it possible to come to your place of business and have a tune installed there? I'm only about 3 1/2 hours away and really don't want anything other than my original pcm tuned.

Yes,

I can also put iton the dyno and dyno tune it if you'd like.

Wish I could do that, but Im on the West coast from you guys!:o

Any idea on when you will have a Tune for the 4.2L I6 for 2006 Trailblazer LT?

We are doing the 06's currently. Sorry if this post says otherwise. Really there isn't a whole lot we aren't covering now adays. Sure has blown up since we started this way back in 2000 doing 94-95 LT1's.

Ah, send me a dyno graph or a datalog and we will get it the next best thing. BTW. I'm still a bit buried but I'm going to send you those new updates in a bout a day or two. I think you'll really like them.

[Bodyslide]

I can't wait, I probably will Drive up one Monday and have you install the PCM, test it out and then spend the night in Charlotte. I am near Atlanta Ga. The wife would love to do a quick trip to NC... Thanks

No worries, maybe I can get a log this weekend as I plan on testing whether the limiter is indeed still in EFILive (think it is, but Im not getting my hopes up).

I want to flash my PCM with the new tune you are working on!! From the sounds of it you saw some pretty good gains!

[Bulldog]

If I come by your location in Charlotte do I need an appointment or can you get me in and out? I can call about an hour prior if necessary. I have a tune from Wait4Me but I would like to see what your tune can do on my other PCM which is also tuned but not to my satisfaction.

[JJ]

Thanks Alvin , I'll call a couple of days before hand and set up a time and date. Don't think I'll need a dyno tune as my racing days are a long time behind me.

[blandmiller]

I just noticed that I have been posting on this topic which is in the 'basic vendors/groupbuys' forum. I would like to continue the shift point topic, but not in this forum. If someone would like to open a new thread in the 02-07 Engine & Drivetrain forum, I will participate.

I don't want anything I state as opinion or fact to reflect on any vendor products or methodology in their own forum. I am trying to be considerate of the supporting vendors.

Hi there, we are often in and out of the office at various dyno tuning events, so yeah you need to make an appointment. We use a mobile dyno so we are in different locations throughout the week, best thing is just to get up with us and find out where we'll be, and we can flash the truck for a street tune in between our dyno tunes. Or we can always dyno it if you like. 704-307-4227.

That would be fine with us. In fact there would be no installing/uninstalling of the PCM in that case...we can take care of the tuning all through the data link connector under the dash without even popping the hood. :D

Probably should pop the hood, just to make it look good!:D

[Bodyslide]

Can't wait.....:yes: :yes: :yes:

[ScarabEpic22]

Maybe for you, but I like being able to not have to bother and just plug it into the OBDII port and click "flash"!:p

[Kelly_PCMforless]

I think it would be more fun to leave it closed, stand in front of it and wave my arms as if conducting a magic spell...while Alvin is inside flashing the truck. :D

[blandmiller]

The dyno plot is labeled as a "bone stock trailblazer I5". The curve looks like a stock Trailblazer but seems to be lower than any stock curves I have seen. Are you sure that the plot is of a Trailblazer Inline 6 and not a Colorado/Canyon Inline 5?

[teebes]

Just ordered a tune for my 02 and can't wait :D

Now time to get that CAI installed and ready :drool:

It is our personal truck, yes it is an I6.

[ScarabEpic22]

Well, I got the new file Alvin sent me yesterday and flashed them to my TB. Cant say I notice a difference besides it seems to pull harder past about 3500rpm to 5800rpm (really good thing BTW), but I only have about 15-25mi on the new tune so far and I dont know if the PCM has adapted to everything yet.

BTW, I cant believe how much faster my TB is on 92 than 87, its crazy!!:eek: Still waiting for a full tank of 92 to compare mileage and see if its worth it as the extra 4 bux a tank is kinda expensive.

:yes: :D By the way, thanks for the quick turn around - :woot:

[btisdale]

I just ordered mine. It says that there is a 3 day delay. How true is that?

[Kelly_PCMforless]

True, because my core computers come and go. I should have more TB cores in any day now to fill orders with.

[jover]

how long is this deal going on for?

[jdjohnson50]

I just installed my PCMforLess tuned PCM and a K&N CAI and I couldn't be happier. The response off the line is much improved. I don't street race or race at the strip but the over all driveability and acceleration is much better. I hope I see some MPG improvement as well, but if not I'm not going to complain. Great job Alvin and Kelly. :D I'll certainly spread the word around to all my Envoy buddies here in sunny South Florida.:cool:

The K&N CAI really growles at WOT :) . For normal driving the sound is meaner but barely noticable.

Glad to hear you like it. I appreciate the feedback. Give it a couple of days.. the tune only gets better with about 200 miles or so.

[kevz28carter]

i have an 06 tb ext
how soon will the tunes for the 06 be ready
also come TAX time i will be getting a cai
would i need to have it tuned again?

We have 06 tunes ready to go. What I can do is go ahead and set it up for a CAI now. There is a difference, its minor, but its a difference..

[kevz28carter]

i also have a 96 tahoe 5.7 4wd 4dr
can you guys do magic for it as well?

[blktbon20s]

you guys still have this special open?
I want one for my i6

[ScarabEpic22]

Yep, call/email and order one up! Kelly mentioned this might be going on for a long time as lots and lots of people are ordering tunes from them on this deal.:cool:

[PCMFORLESS_BH]

Hi,
This is Bryan from PCMforless.com and yes we do have tuning available for the 5.7 in your 96 Tahoe. It seems to be one of the forgotten vehicles with tuners, but we do have programming available for it. 15-20 HP in gains, firmer shifts, better mileage, and I can get rid of the power enrichment delay that makes them so lazy off the line and on downshifts. Check out our website for ordering info.
Thanks,
Bryan

[state08]

if were NOT to opt for GM’s latest calibration/operating system, what would I be missing out on?

[hanskloss]

That tuning is great. Worth of every penny.

[PANGGOY]

i have a 06 TB LS and i got it only 4 of months ago. will a tune void my warranty? i have read a lot about the positive response from your tune and the only thing thats stopping me from ordering one is the factory warranty.

Read the FAQ on their website. It is undetectable. I say go for it.
BTW after posting I noticed that price is back to $139.
It's still a great deal.

Does the tune affect the 4WD functionality or performance at all???

[ScarabEpic22]

What do you mean? Like how it works in snow/ice/etc? No, nothing is affected, I am PCM4Less tuned and drove through snow and junk tons of times this winter, no issues even in like 6+in. If anything, its a little better as you can rev a little quicker, so I can lock the rear diff quicker (thanks G80!).

If you mean shift points, yes, they change them ever so slightly to mirror the new tuned parameters. Thats at least what they did back in like Oct/Nov when I bought my tune, I heard now they dont change the 1-2 rev limiter to 5700 like I have...

[xceebeex]

So the price is now $190 if you want a new ECU? Will the price ever go back to $150?

[elbows8]

hey guys i just got off the site , was wondering how much if i just wanted to keep the core that u send me. and is there any discount for us guys....
