And what about this other myth I heard off, like just say if the car revs up to fast like for instance if I had nos, bmw says they will pick up that the car is performing out of parameter! Did any you guys hear of that also?
BTW your guys are lucky,I got to remove software and when I get the car back it has Anti-Tuning on it. So it takes a few hours to sort out and put the software back via the OBD port. The exhaust is a very quick job.
