Been doing it and been watching afrs and all is well. Anyone else?

My tuner (Jason Carberry) asked me to install mine in the intake manifold, just beyond the throttle body, right next to the check valve for the crank. My logic for doing it this way is, if you're at an idle and your throttle is closed, you want the engine temps to be what the manifold temp is since that air is more stagnant and probably heat soaked. Your charge piping or TMIC would have less heat soak and be a couple degrees cooler than the air the cylinders are actually seeing.

Do those couple extra degrees of temperature matter? I doubt it. Do I have proof this is true and not just BS? Absolutely not. That's just all an educated guess on why he prefers the IAT sensor in the manifold rather than the cold pipe/TMIC.
