I have a SCT tuner that I used to flash my last Mustang. I did contact my tuner, Juggernaut, they said I'd be able to send them a config and they'd see what they could tell me. Just don't wanna go about putting in the wrong fuel!
Recently purchased a '21 GT off auction. Not sure who previous owner was, car was on the auction block a few states away and had to be transported. It has a few mods on it such as a JLT CAI which I know requires a tune. How can I check how the car is tuned and if it is on a flex/93/E85 tune?
