6.7L HO Cummins (2011.5-2012)
Ok, I have owned a several Fords; F-250 7.3 loved it, F-350 Dually 6.0 chipped it and added an intake system, then it ran great, then I blew it up. I bought a F-450 with 4.88's a 6.4, stock and it's a slug. I have given up on Ford.
All you Cummins guys, give me some real advise, I don't have...
