Mine is approx like 97 Cummins above. Daily driver and I get 25+ mpg when I keep my foot out of it. More power I add better mileage I get. Sooner or later I will cross a line of diminishing returns but I'm still upping both power and mpg right now.

Running a 95 2500 4x4 w/265 tires and 3.54 gears.

Haven't dynoed but probably in the 400's. And I get 15mpg right now. Pretty much driving without a turbo since it dosent start to boost until 2,000 rpm. About to switch it out this weekend. 35" bfg all terrains.

89 is 487 on fuel, 972 on nitrous
95 is 601 on fuel.

I've driven both daily, although the 89 is pretty hazy with the big injectors.
