I just removed a H&S. 08 F-450 6.4. I did a dpf delete and ran the no HP gain with the lowest smoke setting. It smoked way too much, did not improve economy and the trans program was really harsh and inconsistant. I would not recommend it in a work truck. The 1999 cummins in my motorhome has a banks kit at 425 hp and does not smoke at all!
