Do I really need and aftermarket AFPR with my ProCharger?

I always plan on running the stock 43.5psi of fuel pressure using my Walbro in-tank pump and I'll be running 30# Accel fuel injectors. I of course will re-tune my DIY PROM bin to compensate for the larger injectors and to control the A/F mix under boost and get everything running right.

I mean just how reliable is the stock FPR? Will it stay consistant or would I need an aftermarket one to make sure I'm always @ 43.5psi?

Thanks!
