The only way currently to reinstall the original calibration is to have it done at a Ford dealer whereby the event is recorded. I guess if you destroyed an engine at the track with an outside calibration while racing and then reinstalled the mountune calibration there could be a false warranty claim. Although I doubt anyone would ever do that.Ken,
Maybe I am still missing something.
Can the MP215 tune be installed on a daily driver then be removed so as to install a custom tune via the Cobb AccessPort (for a track day)?
Then AccessPort removed to reinstall the MP215 tune for the daily driver again?
