I did, they didn't know either :(

Does anyone know any that will work with the 6.4?

One way is to return it to stock, have the dealer reset the tire size, go back home and load a tune, it will maintain the setting when you retune.

I asked this same question about a week ago. My plan is to go to the dealer and while there retune to stock then have them change the tire size. I should get one start on while on a stock file. Then re tune and hopefully be good to go. If this plan won't please correct me.

I really wish there was another way. If I didn't have the spartan I could adjust the tire size with an H&S.

well I'm out on both ways then. I really wish there was a way to calibrate the tire size.
