H&S HD300 questions?

[powersmokin64]

you must have a magical truck or magical programmer because I've put H&S on probably 20 6.4's and every one of them smoked like crazy

It certainly doesn't smoke much on mild that's for sure, but then again a wizard did own it before me so it's a possibility

That is what I am running also, I get heavy smoke till about 15 psi boost if you go more than 1/4 throttle from a dead stop and fairly heavy when the truck downshifts when going to pass. It is not horrible but it is still to much smoke for my taste.
