if your gonna lift it and your worried about MPG, dont lift it.

as far as i know my friend with a 2wd 07 avalanche with a 6" procomp, 35" tires, and a 5.3 gets about 11-14 in the city and like 16 on the highway with stock gears. would probably be a bit better if he re-geared.

hope that helps.

I'm getting ~13 around town and ~15 on the highway. My buddy drove it 900 miles home for me from TX and got like 16 on the highway. He must have been easier on it.

I'm still running the 3.73's, still trying to decide which shop to regear for me.

2.5" leveling kit, 33's on 20x10" alloys, 18 highway 13 city, it was about 20 highway and 16.5ish city before the bigger tires, I have 3.23 gears so thats whats killing the city mileage

2007 NNBS CC 4.8L 325/60/20 Toyos on 10" Lift 4:10 gears and I average 15 mpg all around. If I cruise on the interstate I can get as high as 16.5mpg. I also have the Edge Evolution set on Economy. Dont think it helps much. I credit my mileage to being decent to my gears honestly. Its perfect to get up to acceleration and dont sacrafice many RPMS at highway speed.
