Well you got it tuned that probably hurt some.

Huh? Data shows otherwise, although not a significant advantage...

You have a 4sp, that hurts some

Yes, this 4spd and 3.42 gears SUCK! I'm not even sure why the higher gears are an option, obviously they dont help on the highway and they definitely hurt you around town.

and the way you measure hurts some.

Again, Huh?

I get 22 mpg and thats over 15,000 miles of data. FYI its a 08 Hybrid with a 2/3 drop kit.

07 with 5.3L and 24's = 15.8. The wheels dropped the mpg by about 1.5 mpg.

Some of you guys must be running non ethanol gas. My bone stock 07 Yukon 5.3 4X4 averages 14.5. That is some highway and some stop and go mixed. My truck has 37,300 miles on it.

[Stockfornow]

The average for the truck in the computer says 15.5. It was at 13 when i first got it. I get 15-16 around town, 17 highway.

With my 09 Denali XL AWD I average around 13-14 around town, on the highway anywhere from 16-21mpg. The 16 was carrying 6 people/luggage into a strong headwind most of the day cruising at 80mph on the interstate part of the trip. I had an Acadia for a weekend and it actually got less gas mileage going up to Park City (about 1 hour away). The problem with it is that it needed 5th or 4th gear most of the way up there while the Denali stayed pretty much in 6th the whole way.
