performance modules

[StvsDenaliXL]

:undecided well I was surfing on ebay today, and I noticed quite a bit of performance modules for sale from $7 to $30.....they claim to add +17 to +25 more HP...no tools needed, just plugs in to the ECU and it suppose to trick your computer into believing it is receiving higher amounts of fresh air, which alters the Air/Fuel ratios slightly to offer increased performance & higher horsepower values. Now are these things legit or just alot of bull:confused:
what's your take on this guys and gals

[Trailblazin]

risky (do it if ur under warranty)

[ScarabEpic22]

I wouldnt do it, too risky IMO.:no:

Dont want to have to deal with the dealer/insurance if something bad happens.:o

Hey it sounds like crack for your truck! It seems like a good idea at the time......then something always goes terribly wrong!:D

Big ripoff scam, dont be a dummy.

Its a Resistor, the same kind you can get at Radio shack for a few pennies.

What this resistor does is change the voltage that your Air intake sensor reads ( usually a voltage level between 0-5 volts, to determine how much airflow is passing through the intake, and then assigned a value on the Air/Fuel table that your PCM uses to calculate how much gas to put into your engine. )
Basically, when you put on this resistor, it tricks your PCM into thinking it is getting more air, and as a result, it will inject more fuel into the head. This actually produces a Lean mixture, so unless you're running Premium, you could have some pre-ignition and excessive heat inside of the combustion chamber due to the fact that there is not as much air actually coming into the head.

Bottom line is that its not good for your engine, and a waste of money. If you want to alter your air/fuel ratio and possibly damage your engine, you could bore the sampling tube for the intake sensor a little larger with the same result, or buy your own resistor. You may gain a very small amount of power, nowhere near 17-25 .. more like 3-5, and you will have worse gas milage also.

I figured it was crap:rolleyes: ....it seemed a little too easy and the numbers just didn't add up...I was just curious about it and if anyone had any trial and errors...I'm still looking into getting a CAI, Tune, and possibly an exhaust.:D

Yeah, stick with the stadard performance mods. These guys on Ebay are selling Magic beans. :weird:
I had the Sampling tube on the MAF bored out in one of my cars to produce a simular effect .. when I switched a stock MAF back into the vehicle it got better gas mileage.
A friend of mine bought one of these magic beans a few years ago but never got around to installing it because his car was set on fire, except he only wasted about $5, all the money is spent on fancy packaging.

if u beleive that i got some blinker fluid for ya too thats good for 10hp and some nawwwz stickers thats good for another 5

oh man...those would go great with that wing I am gonna get...its good for at least 20 horses!!:D :laugh:

[rcam81]

And I thought that the prop in my hitch receiver was helping.....:duh: :rotfl:

I have a slightly used muffler bearing in the garage for sale too.:rotfl:

dont forget to realign the keneuter valve when you change those muffler bearings

[rcam81]

And how much anti-freeze do I need for my Corvair????:rotfl: :rotfl: :rotfl:

Oh man....you got one pf those too?? I figure its good for at least 20 horses all by its self.:D
