ok my friend got his diablo tuner last night and we went to install the tune and it say the vehicle already has a tune and cannot override a custom tune. so the guy he bought it from must have had a tuner and never gave it to us
how does he get it back to a factory tune so he can use the diablo?
also he has a speed cal would that make it say it already has a tune?
let me know your input thanks!
