i bought a 01 powerstroke and it said it was faster and it came with a hypertech. well i hooked that hypertech to see if it worked and it gives me a code that says the hypertechscanner can no read the vehicle. so i hooked up my code reader and it reads fine and the code reader throws a code that says its tuned. i cant get the hypertech to read the truck so how do i get it back to stock so i retune it with what i want??
