    Dang seems like the 5.9 was a bit better still, my customer came in with 200K on the clock getting 17 mpg to 19 mpg towing 10K to 12K. I will say thats the highest number I have heard yet most around 10 mpg .

    07.5 6.7 4x4 crew drw 6 speed (stick) 3.73

    I'm not gonna worry or check it anymore. I'm gonna beat it like it has red hair and fill it when it's empty.:D

    refer to one of the other mileage threads that have been started...

    Before I got the injectors and turbo I was averaging about 18 mpg (hand calc.)

    Now I can't keep my foot out of it so I'm expecting around 16-17 on this tank :pimp:

    Just finished 6000 mile towing trip to Rockies. Half was with new MP8 installed. Averaged 9.4 going out. Removed MP8 at Estes Park. Loaded 1800 pounds of red Colorado stone in truck along with RV. Return trip toward home averaged 9.6 ... MP8 helped power but did nothing for milage.
