[QUOTE="decipha, post: 16401544, member: 74327"] I indirectly had to deal with this once before myself. A few years ago a gentleman purchased a slightly used 2015 GT from the dealer local to me here in new orleans. The new owner loaded a canned sct tune in it and just like that it would not run. SCT got involved and they too could not get it to run. He brought the vehicle to the dealer and they loaded a stock tune to it and could not get it to run. So it went higher up the food chain to their manager who called us to diagnose it (we have a strong relationship with this dealer as they drop off new vehicles to our shop regularly for turbo kits). Anywho they dropped it off and I too couldnt get it to run on a stock tune. I started snooping around and found that they replaced the inlet pipe with a much larger one. Neither the owner nor the dealer knew it was aftermarket as it was a very clean stock appearing piece. I kicked up the maf significantly and all was well. Moral of the story is just cuz you purchased it as stock doesnt mean it is. I've personally ran in to another coyote that was bought used and dropped off for a turbo kit install. The owner assumed it was all stock and other than a slightly modified fuel system and 90lb injectors it was. That owner had no idea as well. Not saying thats your problem as it sounds like youve got it figured out but might be a good idea to just verify everything is stock otherwise. Its near impossible to not have a modified mustang in some way or another when buying used in my experiences. [/QUOTE]
