So, if I read the above post correctly; as long as the vehicle is flashed back to stock, and a full drive cycle is completed, there is no "ghost" of the tuned flash that can be found with "special Ford software and equipment" like we've all heard?
Example; If a formerly tuned, used SHO is traded in to a dealership, but has been reflashed back to stock for 3,000miles. Is there ANY way the dealership, or Ford, can tell that vehicle has had an "unauthorized flash"??
TIA
