I just installed a FMIC in my 07 MS3 and CAI. I did a blow through system by moving the MAF after the BOV and before the throttle body. I was working just fine as long as I didn't mash the gas pedal(If I did it would cut out like i was hitting some sort of boost cut or something like that), so I moved it back to the CAI. Now I am getting P2177 and P0300 codes. I cant win with this thing. If you have any suggestions please let me know.
