Performance chips
Does anyone have experience with the Gorillachipz? I hace a stock LS1 with 92,000 on it. The chip claims to give an additional 36 to 58 mor HP with any intake. Since air flow is the key to performance, I wonder how well it can actually work without me making the flow improvements.
Are these devices legit? Do the create any unforseen problems that I may not be aware of? I certainly don't want to damage my computerized system. Can the chip be removed and the settings returned to normal?
What am I missing here?

don't waste your money there, go to Alvin at pcmforless for your chip. I've never seen just a chip make anywhere near that performance increase on a stock unit

If a chip would make such a diff. don't you think the General would have put a switch on the dash for that boost?
Save your money. Its like the air foil 15hp or the T/B bypass 10hp etc.

Thanks for the input. I fugured it was too god to be true. The best improvement would be a larger cold air intake and throttle body up front and exhaust system upgrade? Is there any validity with the external programmers available?

Exhaust yes, and the programmers are not useful in terms of engine performance improvement. They are capable of improving shifts in an automatic, and in changing fan settings.

Actually his profile shows a 94 which would be a LT1. But, none the less it does not use a replaceable chip. You would need to have the computer reprogrammed. Again, talk to www.pcmforless.com They offer excellent service and are honest about gains etc.

I think this is one of those cheap "high performance chips" that is basically just a resistor that plugs into a connector somewhere. Not really a chip or pgramming at all.
a couple of the guys on the mustang forum I posted a few posts up explained it simply:
Appears to be a 4.6K resistor. Available for <$1 at your local Radio Crack.
It alters the voltage coming from your intake air temperature sensor and makes the EEC think your incoming air is colder than it really is, which means it leans out the mixture.

I don't think it would do anything to the mixture. In all the car tuning software I've seen, IAT only affects timing, not injector pulse width.
The resistor is most commonly used on forced induction or nitrous set-ups to lower timing when the builder doesn't have the capability to tune the ECM. On the flip side, some guys use the resistor to make the ECM think the incoming air is below XX temp, which allows full timing advance. Regardless, messing with the IAT sensor will never net any performance gains greater than a cool evening will.
