Now if you have a piggyback unit installed, that's a different story. Just like the MSD81 ECU on the 335's that BMW designed to combat piggyback control units. The car would through a shadow code that indicated that the car had been modified. However, with our flashes no such thing will happen. The tune is completely transparent to the dealership.

What about if the car is throwing codes related to the tune. Won't they catch on then? I know with the 335's this happens all the time.
