anyone willing to help me out or share a good mileage tune for an 08 auto 6.7? the one i have doesnt seem to be much of an improvement over stock and im not even sure it was written for a 6.7 auto.

Ditto. Also a log to go with your current tune to make sure it really is doing what you wanted in the first place.
