I have better luck on the lottery than this chip giving any power.

We don't chip.
We tune.

Is it a 52 cent resistor from Radio Shack again?

i'll be honest. i've tried one. it wasn't on my 2011 though. tried it on my old 2000. all it does it make the car think that the air going into the intake is cooler than it is. caused a CEL because it screwed up one of my o2 sensors. it "might" have improved mpg a little but it sure wasn't 7mpg.

This is an old trick called the IAT resistor mod, often used at drag strips to battle heat soak by fooling the engine into seeing 55*F (IIRC), which puts it in the ideal timing range.

As many people have discovered with GM's LS motors, the Intake Air Temperature sensor itself gets hot under heavy use (drag strip). That heat changes the resistance of the wires in the sensor, making it read air temperature as higher than it actually is. By changing the resistance, you put it into a range where the engine is not pulling timing (losing horsepower) because it thinks it is seeing hotter air.

The idea is not necessarily a bad thing, but is only used at the track under controlled conditions. If you keep the resistor in their all the time, you can harm the motor through detonation with too much timing when the air is actually hotter than the engine wants.

To benefit from the good part of the idea, move the IAT sensor to a better location where it does not get heat-soaked and reads close-to-actual air temps.

On my NA setup with the Camaro, we moved the IAT sensor to the air filter of my CAI, whcih was down near the fog lights. The stock location is between the radiator and engine, and would often see 30*+ over actual temps, which meant slower times at the track.

Bottom line: move the IAT if you want to improve your track temps.

Oh, and the resistor costs $0.30 at Radio Shack.
