Right now I have the IAT sensor just zip tie'd out of the way in the engine bay. Should I leave it there or should I extend the wires and run it into the intake piping pre-turbo?

 

To me, I believe you would want it post turbo for tuning reasons... My guess is so you would get a real-time intake air temp, but I can't say for sure, only because I only know a little about Turbos...

Just a thought...

 

thing with post turbo is the sensor is only held in w. a rubber o-ring, even 0.5 psi of boost will blow it out
