    If the map has been left on the car - very very easy to tell. It would show up as soon as they were to try an istep update for starter.

    If the map and been removed and put back to stock - more difficult as their is more investigation work to do and would not automatically be able to be checked by a dealer. That's when Germany become involved to look for max boost values etc
