Don't install that "mod chip" in the IAT sensor. It's just a resistor that you put in place of the sensor. It's a gimmick. Throw it away. BAD!!!

Intake Air Temp sensor. It's a vital component, the ECU uses that value to determine the correct amount of fuel and timing to run based on outside air temperatures. This "mod" basically tricks the ECU into thinking it's very cold outside so it runs more fuel and more timing, even though the air it's sucking in is actually very hot. Can you say DETONATION?

Detonation occurs when the mixture is lean. A rich mixture will make your car sluggish, eat gas, burn out your cat, and get carbon deposits all over the place.

Thanks for the correction, yeah I was thinking about it backwards. Either way, it's a terrible idea.
