I really want to put a tune on my FiST to wake it up but I'm hesitant to because of my warranty. I have an aftermarket warranty and with prior experiences with other ones I know they can be a royal PITA. From what I've gathered if you took your car into ford they can tell when the car has been flashed, just not what exactly it was. So I guess my question is, would an aftermarket warranty company have the same access to this information?
