You guys with your stock cummins' are leaving A LOT of mpg and horsepower at the pump. I had a 95 2500 4x4. Twin turbos, 435 injectors, lazer cut delivery valves 4000 govenor kit and a lot of pump work plus a really good tranny. I averaged 23-24 on the freeway and 16 towing. That was at 600 RWHP. Now I have a 07 6.7 auto 2wd 3500. I have deleted the EGR and DPF all the way to the turbo. Added a free flowing 4" exhaust, AIRAID intake system and a H&S mini maxx programmer. It gets 24 on the freeway at 65 and 15 towing at 65. Its close to 500 RWHP. This is my old 95. click it.. VVV   My 07
