My alternator crapped out on me only 20K on the car my son's 07 Mustang GT's alternator crapped out on him last year at about 20K what's up with that?:shrug: I had my car towed to the Ford dealer and they changed it under warranty ignoring the Whipple. It was due for a state inspection so I told them to see if it would pass. It was running a Torko tune but passed without any problems. So I was happy about that at least.
