    Is that calculated by taking your distance traveled between fill-ups divided by the gallons pumped in or is that just off of a display? Displays are never accurate. I can understand a 5 speed diesel getting better mileage than a gas truck but not that high. I have a 99 4.8 auto, just got 16.5 mpg (actually calculated, not from a display) driving 75 mph on a hilly highway.

    I used to get 17.6 mpg until I put 20" Denali wheels on. Now I get 15.6!

    How do you feel about your long headers? How is your low end torque? The instalation? Trying to make up my mind!

    not surprising, my uncle has a 96 ram diesel that got in the low to mid 20s. My truck gets about 14mpg but that is all city driving no highway, rarely get above 45mph.
