Go price out powerstroke injectors vs Cummins injectors :redneck:. PS injectors are at least double the price. Single turbos are close (aftermarket). But twins, the powerstroke is double. programmers are all pretty similar though.
Just go to any local dyno event, compare the two. Dodges almost always take top honors, with exception to some chevy's every now and then. Fords usually aren't even close. It's not just because of issues, it costs a lot of money to get the 6.0's and 7.3's up there. The 6.4 would hand me my ass with just a HOT tune, even when I get my truck back on the road with the goals I have. Also notice the vehicles all of the mechanics and shop owners are driving :awesomework:.
But my point is you have to mod the cummins to get any power out of them...
