Re: Drove a Hummer for the first time in my life last night!
With a tune dont expect to pick up more than around 1mpg, remember these trucks are very heavy and wont respond to mods like your car (or any light car for that fact). I drive mine quite easy and since the weather got cold Im bouncing between 11.7-11.8, best I have gotten with mixed city/highway is 12.4, have not road tripped it yet without a trailer (2000lb trailer with my 2 jet ski's) and I got 12.2 over about 1000 miles. I would say 13-13.5 straight highway MPG is possible if you keep it 70mph or less.
