Re: what are you guys getting for mpg?
I know the mileage or fuel economy reading on the dash isn't very accurate but my 2011 Sierra with 6.2 - 3.42 - 4x4/z71 says 16.8 with mixed driving. I reset it to see if I gain any mpg's with the diablo tuner. Probably not but the tuner really woke the 6.2 up all across the board. K&N filter, no cold air or exhaust mods
