    So how does the ECU tell what the air pressure is at? Maybe that's reading high.

    It doesn't. It just reads mass air coming in, and AFR (narrowband, mind you) of the air going out. Its why going BT on AEB sucks

    Possibility lukas, Barometric sensor, F96, perhaps it's reading you're at a high/low altitude instead of sea level, therefore thinks you are attaining a higher boost level than you actually are.

    Located in the ECU plastic box, and can be monitored with vcds.


    Sealevel vs. 6000ft fucked with my boost gauge by about 4-5psi, read higher at sea level.
