No prob never played with Ho pump but hard to beleave it is affecting it that much would of thought our trucks would have had closer numbers since turbos are similar and fueling boxes are close. Just diffrent injectors and pump. I know your turbo is a little larger but I think on mine I am overfueling the turbo because Between 2 of my runs turned the tst down from 9 to 6 and only affected it 8 hp and never came close to clearing the smoke from looks of the pics on the runs.
