Adjustable FPR questions

I have 42lbs injectors, matching MAF and SuperChip + lot of other bolt ons (by previous owner) I have feeling that engine gets bit thick AF ratio as just from idle it feels lazy and when accelerating hard it sometimes blows bit black'ish smoke.
Exhaust gases also smell rich.. (at the moment I have no CATs.. thus I can smell richness...)

So there is AFPR installed and I was wondering that if the fuel pressure is set too high? I have not measured it really precisely but if I remember correctly it was over 3.5 bar at idle.. (have to check it out again)

How the adjustment works, does it raise/lower base and on-boost pressure both or just other? What I have to disassemble to get access to FPR?
