A friend of mine bought a 2008 6.4 that has a spartan in it. No information about who the tuner is registered under. How does he go about getting tunes for it? There are some nasty transmission shifts that need addressed.
He didnt buy the truck from the person who bought the tuner. The person before him had it only a few months before selling it. We arent sure who bought the tuner itself. We were kind of hoping it would be VIN matched to the truck to prove its not stolen or anything
