I monitored my AIT with a GM sensor in the intake manifold. Stock IX turbo peaking at ~25psi and tapering down to 21 psi at redline, Nisei aluminum pipes, a Perrin FMIC, and a MAP v3 ported intake manifold with heat dispersant coating and phenolic spacer gasket. During WOT pulls the temps were always within 10F of ambient.
Here is a graph comparing the manifold intake temps to the MAF intake temps during a 3rd gear pull. Ambient temp was in the low 70's. The sensors were calibrated correctly and read identical when the car is off and fully cool.
