that is amazing you are getting that kind of fuel mileage, mine is getting 13.5 stock, but that is all in town, on the highway I get about 16.5 to 17, I have 3.73's. Thanks for all the info everyone, would I be better off getting a 20 in rim with less backspacing to avoid rubbing, if yes what amount, and would this eliminate rubbing issues? Also, are you running a programmer, intake, ect.
Not trying to hijack but I had to interject!
I'm getting about 13.5 with about 40% highway. I have the stock pirelli's and drive fairly conservatively. I would love to get those highway figures! I took my truck on a 15 hour road trip at approximately 65-80mph and got 14.5 at best! FML! haahaaha, it's a truck though so I can't complain too much! Good luck with the quest!
