Just picked up a 2011 6.7 with 57,000 miles. New to the diesels. I Just ordered a performance package with the minimax, no limit intake, no limit egr ******, and 5 in exhaust. Just want to make sure i am gonna have a good experience with my first diesel. How satisfied are y'all with the canned tunes on the minimax? and its on a 6 in lift with 37s and am hoping for some better mpg
