You find that a cummins gets away with a smaller turbo than a cat at the same level. I have a w/g 175963 I believe on the shelf. Was thinkin about tryin it. See what happens

they do have alot less exhaust energy in my experience aswell. 171702 BW on a cat or detroit - 550 hp maybe 585, on a cummins its good for 650 all day.
