computer problems
after the motor swap it still does the same thing so i changed the fuel pump and filter so everypart on th car is diff and it still does the same thing.....well i decided to put my hypertech on it to put it bck to stock and when i pluged it in it says the vin number does not match to reset my old car to stock before tunning a new vehicle.....
the computer is the same so does this mean my computer ight be trash and this why my car is not running right?????if so what can i do do i need a new one or can i flash it back to stock and the dealer....
also the car stalls at 5 k and i have to let off of it to get it to shift...
