I know that the N54 has 2 MAP sensors, one in the charge pipe, and one in the intake manifold. Which one is responsible for reading Inlet air temperature?

The one on the chargepipe.

Ok, thanks. To expand on my question, would the mounting of that sensor have any effect on the IAT that it reads? I ask because I recently installed an Active Autowerke charge pipe, and noticed that the tmap sensor no longer sits in the airstream of the tube like stock. The map sensor mount on the AA charge pipe is pretty tall, so the tip of the sensor sits just flush with the inner wall of the charge pipe. Would this affect its readings at all?

[Terry @ BMS]

It shouldn't, at least not much.
