Post your gas mileage!
before the tune on regular, i would consistently get 17 city and 30 highway. that was decent driving around town, and usually doing 120-130 on the highway.
after the tune, using premium, i would still get 17 city but touched 32 on the highway.
something to think about, my old diesel weighing 6500 lbs and running 4.10's in the back with a ton of mods would get 23 on the highway.

Dang auto that's terrible! Haha you don't have some kind of leak do you? And btw this last fill up... NOT driving like a grandma as much... I got 19.4 and I was pretty surprised. But it might because it got much hotter this last week...
