i have an 04 with 140,000 on it, got ppe hot plus 2 set on 8 ,150gph lift pump, trans mods exaust, intake, etc..... on 33x12.5, i was jus curious to see wat kind of mpg everyone is gettin with all of there mods and such, i figured it up and i was only gettin around 17 on highway and around 14 in city, i would have thought id be getting better mpg, so as i was sayin, im jus curious to see wat yall are getting compared to me.....

I'm averaging 20 MPG mixed driving pretty consistently. This thing is driving me nuts with it constantly getting 20 or right there no matter how I drive it. I have gotten as high as right at 23 though before. PPE's timing in the lower MM3 of fuel is a tad low for the best milage.

Mine gets about 16-17 daily driving to work and back,and 20-21 on the highway.Thats with it being about 100hp(give or take) over stock.

18-19 depending on my driving, this may improve with a couple issues I corrected. I figure with a 4x4 dually I can't complain...

city 16-17mpg, highway 70mph > 20mpg, highway 80mph > 18.7mpg, running what i have in my sig...265/75/16 tires

I'm getting around 20 mpg mixed driving and about 22 highway and 14 pulling 1oooo# boat.

Mixed driving I get 18-19 summer and 16.5-17.5 winter.

6-10mpg pulling. 12-15mpg empty. 15mpg is rare.

About 19 mostly highway, stone stock.

I am only getting 10 hand calculated in City
Towing 10,000, 8-12
Not to much Highway but guessing 18-22.

16.6 mpg over the last 11,702 miles in 18 months. That is mixed city and highway with minimal towing. Interesting thing is, and the reason I started keeping careful track, I was averaging a touch over 19 mpg 11,000 miles ago and there has been a very steady decline. Haven't figured it out. Changed air and fuel filters, tires are good and properly inflated, no changes to where or how I drive it. Total mileage is 70k. It is a mystery. Truck is bone stock.

I'm getting about 16.5 (hand calc) - averaging 30-35 MPH per the DIC. I gave up a couple MPG between going from worn tires to new ATs, and putting on the ladder rack (over-cap model, hangs out beyond the cab:(). I run the sixgun on 2 or 3 and drive like an old fart mostly.

03 lb7 with 341,400 miles getting 21mpg highway :) dont know about city though :(

With a Bully Dog on Performance, cold air and a 4" Turbo back it got 22ish driving on the street. 26 going down a highway at 80MPH!! according to the diplay on the dash..

Hand check it and I bet you are closer to 18-20 going down the highway. The DIC is notoriously false in stock form, and when you tune it is almost guarranteed to be off. I know my wifes G6 is off 12% straight from the factory, and have heard it is optimistic by about 10% in most all of them.

well i would hand check it but it got stolen a few months ago now... its stripped right down and beaten sitting in a junk yard. hense my display picture..
