Does it smoke at all when your foot is hard down? Could possibly be weak mixture if not.
@ 20 psi, the boost has obviously been 'adjusted', if the pump hasn't been adjusted/adjusted enough, then it'll be weak under full load at higher revs. Easing off decreases the load and boost, it may well have the correct air fuel mixture then.
So does it smoke when up the revs (at least 2500rpm) and foot planted hard down?
