Jacob you should not even be thinking about a IAT sensor with your build.
Hook it up to a happy knob or an ICCU.
Run a real Air temp sensor with a NPT end and thread it into the IC piping or UIM.
A dual temp gauge for before and after IC temps would be ideal.
Your going to have to scale the MAF down at somepoint most likely with an AFC so could just get the ICCU and that would take care of the IAT. Or you could run the Lq4 sensor with the built in IAT. The LT1 Style maf is only going to give a little headroom over the lq4 so i wouldnt throw out the idea of using it.
