Look like I should switch over to the BJYL binary for the Vortec/TBI/ Export, or similar binary, to be closer to the objective of tuning the Vortec with 454 throttle body and Cop Car injectors. Then set the fuel pressure regulator to approximately what it needs to be and electronically tune from that point.
