dont put your IAT in the location i put it...hot air heat soaks it because the bloc off is not perfect so some engine air get in at idle when no air is blowing past the headlight my IAT read 140 degrees at idle today!!! moved it into the pipe and i read 2 degrees above ambient...the inaccurate reading really messed me up when i launched against some ricer today still beat him but it bogged hard.....def stick with putting it in the pipe away from the crossover ill take pics later so you can see
