I had a mechanic install a Ford Performance Pack on my 2017 Ecoboost Convertible Mustang. It killed everything, the car won't start. It's now at a Ford Dealer and they can't seem to find the problem either. They have reinstalled the tune a number of times, but no luck. Has anyone ran into this problem or have any suggestions? Thanks!
