Mine's got stock 17's and stock tune. Only changes are a K&N CAI and Magnaflow exhaust. The overall average in my 11k miles is 15mpg.

Thanks guys. I found a 07 2wd ecsb LTZ v max has everything w/ 26k for 21k just cant make up my mind about a 2wd..I like my 4wd. They can hit 13's pretty easily though right

They can hit 13s, but not easy.

i have mine tuned for 89 octane. I picked up 65 hp and 76 lbs on the dyno when they tuned mine so i could not imagine 93. I average 18 and i get 21 on long trips.

On stock tune I only run 87 Octane Chevron, when I am running my Black Bear Performance tune I only run 91 octane

3.73's. yeah i wouldnt roll with the 4.10's. my dad has them on his 2500 hd and my truck actually pulls better, you really dont know their is a trailer back their sometimes. But that is me, drive both and see what you like

Cause your dads truck is quite a bit heavier. 4.10s will get you off the line better. 3.73 are better for highway speeds.

with alot of bolt on's! I will let you know once i get mine re-tuned cuz i will go to the strip. I was at 14.8 but i have my headers now and once tuned they should get me into the 14.0 range from what i have heard
