A customer of mine has a 06 or 07 dodge 2500 mega cab with an 8" lift, 37" tires and 22" wheels. for performance he has an intake, exhaust, and all kinds of chips and programmers. Anyways, he swears up and down that he get 27mpg on highway trips. I dont see how that is even possible. Most people I know with diesels, regardless of brand dont get over 24mpg with stock tires. I only get like 17-18 on the highway with 35's
