That was with my 2004 Dodge Black Sport 2500 quad cab 4x4 with the High Output 5.9L Cummins and auto tranny. 19mpg was a average of city,country and hyway combination driving aggressivly! Could get 21+ on a hwy trip. Towing anything heavy would drop it down to 13mpg. The Edge programmer didn't do anything for mpg's, but made it ALOT more fun to drive! That's the only truck that i miss out of all the ones i had so far. The new diesels won't get that kinda mpg's anymore.

 

15-17mpg according to my Average MPG counter. Probably has a lot to do with getting on it a lot though.

 

Im getting about 16 average with my 2000 Sierra Z71, 5.3 ext cab on 265-75-16 tires soon to be 33's.
But like him ^, I get on it a lot.

 

You know what kills me is I used to own a 02 Mitsu Lancer OZ-Rally. I thrashed that thing constantly(even though it was slow) and still got an average of about 28-29mpg.

 

15-16 in town 18-20 hwy.

i know what you mean charger, i kinda miss my subaru
