Sorry for not answering your previous question. I have 2v7 flex fuel ECUTune software running 370CC redtop injectors, a walbro HP fuel pump, and a RRFPR running 6:1 for added flow.

If your base fuel pressure is 45psi, I get the following:
Base (psi) 45
Boost (psi) 15
FPR rate 6
Injector Rate (45psi) 370
Pump Head Under Boost (psi) 135
Injector Pressure Delta Under Boost (psi) 120
Injector Flow Under Boost (cc) 604.2074699
With a BSFC of 0.75 and HP of 450, it looks like you are on the bleeding edge of what your current injectors will support. What AFR and Duty Cycle are you seeing with your current setup?
