Update the firmware. Reload the custom tunes. If the car runs like trash with the aftermarket tunes but fine with the stock tune, the tunes probably are no good.
You can pull serial number and computer codes using device info when the tuner is plugged into the car.

Yeah I tried all of that before. Still didn't work...SCT had me thinking the tune that came from the factory was wrong. SoOOOO I went to Ford they chaecked the computer flashed and found out there is nothing wrong with stock tune on the Mach. Then of course I got the lecture from the tech about using tuners on our cars....
