Prelude 345cc injectors w/ B&M FPR only

I've got some Prelude 345cc injectors and I wanna run those in my 93 Teg w/ only a B&M FPR. Just to drop the pressure down some. I've put them in with out a B&M(just stock regulator), and they ran fairly rich on bottom end, kinda laggy, but real nice under boost. That was running them without the resisitors on the injector wires as they are peak and hold and my car is saturated style. Of course I'm also running a 340lph intank pump so I was hoping that maybe I could drop the pressure down a little bit for low end. Do any of you guys think this would be ok or anyone ever do this? I could probably just try it but that would involve work.

Thanks in advance.

you want a fpr that drops pressure at lower rpms?

I think MSD makes an boost sensitive FPR. Are you running a FMU? From what you said it sounds like your just running big injectors with nothing to manage them.
