Hello everyone...new to the forum. I recently purchased a 2009 Mustang GT from a dealer. I did not know until I got home that it had a tuner. Upon hooking up the tuner, I noticed that the car does have a custom tune loaded. I have called multiple companies trying to get lucky and find who did the tune, but have not been successful. The dealership was supposed to try to contact the person who traded in the car, but I honestly doubt they even tried. The car runs great, but I have no idea...
