Hav'nt taken my foot outa it since my ddp 90's and prostreet 66/14 got here. finally got a chance with 300 miles to go..........21mpg's hand calculated. the best I could get without them was 18mpg's. so happy!!! I know some will try and prob. say I did something wrong but I didnt. 550-600ish hp and 21mpg's gotta love the cummins

 

35" tires and 21mpg? Too cool.

Sometimes I wish I had 3.73's. My best ever was 22.3, but that was driving very slowwwwly. Also, I'm no where near your hp levels, and I have small tires.

These trucks are pretty darn amazing.

 

Chet, your summer seems to going great!
Wish mine would cooperate a little.
Oh yeah, those ladder bars look slick too.

 

preciate it lebo! my summers great but ready to get back to raleigh.

 

Yessir... there when the boy calculated it... I was impressed.

 

Followed it up today after the chesney concert and SMOKE with a 20mpg
