my gas mileage stayed about the same if not a little worse just because I probly romp on it more knowing its faster lol. But as far as I know the hypertech sucks for gas because I have personal experince with 4diffrent cars with hypertech and only noticeable thing was the trans shift points. and that was on a 04f150 crew cab, 96 Tahoe 4x4, 03 Hemi Ram and then a 01 Tahoe and no noticeable power upgrades or fuel mileage change. Thats just my experience with hypertech programers...I love my superchips and my buddy loves his too.
