I know this is for an M35 but I need help?
I have put on a plenum spacer, stillen exh. and cold air intake. I would like to get my ECM flashed. The guys at UpRev have not done any M35s so they can only help me if I jump thru hoops. They were very helpful on the phone. So who does a good job a flashing the ECU in a 06 M35x?
