You'll be fine. The RRFPR essentially runs the fuel pressure at a higher rate, effectively driving your injectors harder @ a higher duty cycle to support higher power levels. Proto have been doing that for years. I run 37lb 944t injectors in my stage3 build and they'll support ~600HP+ with the Proto RRFPR and ECU cal.

You can fine tune the fuelressure ratio with an adjustable RRFPR (like a BEGi) to get best A/F ratio etc...
