336.6HP/325.5TQ stock with k&n

today with Vector tune and k&n

382.7HP/377.2TQ VMT & k&n


Chris I've said thanks before but the numbers say it for me!!

46.1 HP/51.7TQ gained the best $$ spent on a modd.

Very cool. Have your dynos handy? Would love to see where the power is being made.

Is the AWD *that* big of a drain? I think the AWD tune only free'd up 20hp/40tq?

[GTPprix]

No, we picked up 40 horsepower in third gear as well on the AWD. We advertise gains of about 20-40 across the board, not just peak :)

[TrailblazerSS]

These results and the tune is nothing short of incredible!:hail:

Nice! So to work backwards for useless bragging rights...A 395hp stock motor now puts out _?_hp after a Vector tune. 425hp maybe? As long as it's more than a stock GC-SRT8!

[GTPprix]

Well his original dyno of 337RWHP assuming about an 18% driveline loss his truck was making about 410 or so horsepower at the crank. After the tune with 383 or so to the tires thats about 467 or so at the crank. This is obviously not an exact science of course and should be used purley for educational purposes lol

(Conversely if we use a 15% driveline loss his stock dyno is about 396 horsepower and after tune was about 450 even at the crank.)

[02redhawk]

Very, very nice.

[BIGBOS]

Wow, that is incredible.....that pretty much puts the icing on the cake about this tune :)

[BLUBYU]

I know peak hp in 3rd was at 4900 rpm
I've asked the company to email the #'s too me.
The trucks increase was as posted by Vector across the board like crazy
low rpm was still a 26 hp and 35tq gains!

Stock simulated ET was 13.77@99.2

Modded was 13.29@104.5

[Scalarrthu]

All of this makes me very happy!

[Envoy Fan]

Great increase.:thumbsup:

Would like to see dyno sheet.:yes:

[Dacomputernerd]

Great increase.:thumbsup:

:iagree: :D Roughly 450 at the crank :drool: :hail:

[Fishhunter911]

Very nice numbers!!! Woohooo I own a 450 hp SUV :duh: heheheh would have it no other way!!!

[Bergie]

Hmmm... I wanna see the chart.

C6 or GTO LS2 with headers and a six speed are about 380 on the dyno

someone tell me how a tune will make that much power?

I doubt it.

I doubt it.
With the amount of TM programmed and timing intentionally pulled on this vehicle by GM, I don't doubt the dyno numbers in the least. I want the dyno charts for a different reason - to see where the newfound power is being made. Peak numbers are somewhat interesting, but nowhere near as much as average power (to me).

Here we have another person doubting the tune before they try it. WTF is with you people. Are the chassis dyno results and the 13.5 1/4 mile times not good enough? I suppose I just dont know a damn thing then.

This is a thread with the first AWD chassis dyno results. Obviously the 2WD will vary....

Well I did gain 1/2 a second at the track in my AWD. I too was skeptical. But I found out it is really there.

[ScarabEpic22]

Sweet! Thats a lot of power freed up by simply changing the programming!

Thank you... More proof for those who are doubting it. BTW, what did you compute your 0-60 times to be after the tune?

No one doubts the tune works...but we need to see hard #'s. This goes the same for the intake / exhaust kits that are sure to follow.

Simulated runs are N/A...did I miss a post with an actual 13.5?

Yes you must have missed it. One of our other members that was also doubting the tune, said according to physics it was not possible. Chris then tuned his computers and sent them back to him so he could test it at the same track he ran his baseline tests on.

I do not understand how there are so many doubters....
I told everyone how great this was over 3 weeks ago.....

I now have installed a 3000 stall converter and I must say that I think I'm in the 12.90 range. The truck rips out of the hole now. In a heavyier SS silverado this converter gained .4 in the 60' and .7 in the 1/4 mile.
Some of the improvement over the GTO and the C6 is in the intake manifold. It makes alot more torque than the flat one.

I wish like hell that there was a drag strip open here in Michigan so I could personally
shut all of the people up that keep trying to dis-credit the POWER
of the Vector tune.

Thanks again Chris and Kirk (Kurt) for your efforts.

[TBSS]

Not everyone is a doubter (though this seems to be the only people some of you are focusing on), some of us just want to see the data. Not necessarily to allay doubt, but to see where power is made, become more familiar with new vehicle behavior, share in the excitement, etc.

Regardless, timeslips or video or graphs shouldn't be that difficult to produce, right? In the age of scanners, affordable video cameras, dynojet files sent over email, etc., what's the big deal if someone wants to see some data? I don't get a lot of the resistance here. :confused:

[ScarabEpic22]

So on that 3000 stall converter, what does that do compared to the stock one? I dont know that much about converters, so please tell me what a different one will do. And, what is the stock converter? Thanks.

[ttdolson]

The new converter allows the engines RPM's to rise a little higher (In this case from 1700 to 3000).
When the engine revs higher it allows the transmission to launch in the engines "Power band" rather than at a low rpm which causes the engine to work harder/slower.
The torque is multiplied at a different rate also. (more torque then stock).

[BIGBOS]

I was thinking about doing a converter down the road....but it does throw some of the driveability out of the car.....it just takes a little more persuasion of the pedal for the car to move.....but if you floor it watch out....

My old car had a 4000 converter behind a 370c.i. LQ4 motor with an F1 procharger on it......that thing sucked to drive on the street...but if you want to go fast :thumbsup:

I think in the future I would do a 2800-3000 vigilante converter with a shift kit....

Thanks...great news

Also, I thought the stock stall was more than 1700 ( can anyone confirm? )

Plus watch the already wonderful gas mileage take another big hit....:crazy: :laugh:

[ScarabEpic22]

Thanks for the info.

But, doesnt installing a higher converter remove some of the towing capacity? I mean I love to go fast, but I still need it to tow at least 5000lbs easy.

[BIGBOS]

Its possible, but most of the time when you get them installed you can have a lock up switch installed to lock the converter in high gear.....I'm sure that would make it a little easier to tow

[TBSS]

The way I understand it, any converter that increases your performance can, to the same degree, decrease your ability to tow. When not 'locked up' at highway speeds your converter will 'slip' more and generate more heat, potentially shortening the life of your transmission (your transmission and your torque converter share the same fluid). Towing compounds this issue. If you subsequently have a transmission failure and your aftermarket converter is discovered, you will likely have voided your warranty. :eek:

If you really need the ability to tow, I would stick with the stock converter. :yes:

[TrailblazerSS]

Thank you... More proof for those who are doubting it. BTW, what did you compute your 0-60 times to be after the tune?

When I plug the 1/8 time & speed, 8.667 @ 82.1 into the 0-60 Calculator (http://www.wallaceracing.com/0-60_equation.php) the answer is:

4.63 sec. ! :eek:

[ttdolson]

Well there sure are alot of opinions on the Converter....
Since I have one, I guess that I'll comment on what has changed.

"Nothing"......The truck drives the exact same (When driven normally), But when you do a "Spirited" launch the converter revs up pretty good.
As far as gas milage, I have not missed a beat on this front either. The gas milage is the exact same (When driven normally).

The only difference that was noticable is that Driving on the freeway @ 80mph the RPM's are about 200 higher than stock.

As far as the "When the trans blows the dealer will see your aftermarket converter" comment......
No they won't.....Especially if its an OEM converter....(That just happens to have a tow rating of 6500 pounds with a weaker trans)!!!!

Anyhow, that's all I'm gonna say about that.

What kind of converter did you install? Is it the converter out of the 4.2L Trailblazer? If so, then it makes sense that it would not be found out. I presumed that it was an aftermarket converter that is painted a different color. Great if it is a TB converter.

It's also great that driveability has not decreased as well as normal launch RPMs. That is usually a big downside to higher-RPM converters, that you lose driveability, and you must give your vehicle a lot more gas to get it moving (losing MPG in the process).

The part that confuses me is the higher RPM at 80 mph comment. Your crusing RPM should be the same - your gearing has not changed, and unless the new converter does not lock up at speed (this would not be good, trust me), your cruising RPM should be exactly the same.

[ttdolson]

It may have just been me..I will post some rpm / speed ratios and try to compare them to the rest of the group.
I really like the converter. And yes you are correct its a trailblazer I-6.

[Bergie]

Like I said, show me the chart.

Its easy to be a keyboard racer.

No TUNE alone is going to make 380rwhp in an SS. Sorry.

[BIGBOS]

Well you got to figure he at least got a 50HP increase.......

TrailblazerSS went 13.5 from a 13.9-14.0 stock....he has the tune.....its at least gonna take 50HP to knock it down that much

[BLUBYU]

The point of the post isn't that my truck makes 380+HP but that the tune was worth the hp/tq gain and yes I'll will post the charts when I can.
Yes it'll probably be the weekend before that possibly "working and all" but I will post it!!

I believe like TraiblazerSS. Dynos are great gauges but all I care about are
the real life ##s ET's and trap speeds!!:yes:

I'm sorry but that is just insanity! You are pulling numbers out of an N/A engine that a chipped turbo or supercharged vehicle could get. This HAS to be the biggest gains for a tune on a N/A vehicle ever. I'm not even joking, I've never seen anything with that high of PEAK gains. :m2: :D

Also how is the 2WD model under that much power? Does the truck actually get up and go, or does it sit there spinning the tires. I've been kicking around the 2WD model since I've found an LT within an hour or so. My biggest fear is just being on the road and punching it and losing lots of traction, bringing a frown to my fact knowning all that power is being pissed away.

Sounds like you need to invest in some Drag Radials if thats a concern. I have a 2wd SS now and thats not the case. I'm on the list now as far as the tune goes, and i'll let you know if it really will smoke them from a roll......

Yeah I figure drag radials will be required but are there even drag radials made in our 20" size? I'm not about to drive around on the street with 20s up front and 18s in the rear :D

Depending on the quote I get tomorrow from the dealership, I might be picking up a 2WD on Wed. It will be at Chris' shop that same day getting the tune if he is available. I fear having traction issues just like my two cars now, I hate it. :mad:

[NVR2FST]

I think everyone is way to hung up on these dyno numbers. They are only good for A to B comparisons. I have the tune in mine, and according to wheel speed (through a program on laptop display) my truck picked up 0-60 perf. Stock it went 0-60 in 6.02, after the tune (with the traction control kicking in) it went 5.72. I'm assuming it would be in the mid 5's w/o TC.

As far as N/A gains, I can't comment since I haven't dyno'd mine. I don't understand why GM left that much room in the tune either, but the gains are possible. Heck, I can't understand why my N/A 306 in my Mustang puts out more than most blower cars ;)

No, we picked up 40 horsepower in third gear as well on the AWD. We advertise gains of about 20-40 across the board, not just peak :)

Chris someone pointed out to me that your 2nd gear dyno pull didn't have the HP and TRQ curves cross pathes like they shood at 5252...do you know why this is?

Nice job on the tune and upcoming CAI...would love to hear a video of it at WOT...:laugh:

I know peak hp in 3rd was at 4900 rpm
I've asked the company to email the #'s too me.

Stock simulated ET was 13.77@99.2

have to give the "Simulated 1/4" some credit...look at that!!
