I'm not exactly looking for smoke, but was more or less expecting some... maybe a big line kit might help?

Hey everyone, I've owned my 99 cummins for a little over a year now, its got the adrenaline, 5" straight pipe, i was told injectors, but not sure, was told some tranny work, and again, not sure!! Feels good though....raptor lift pump aem intake also. I'm getting almost no black smoke outta this thing, anybody know why?? Pulls like crazy! Fuel pressure is about 14 at idle, but dives down pretty rapidly the farther you push the pedal... down to about 5.
