1:1 OE FPR and a standalone should be a nice working combo. No need for rising rate unless your using winky little injectors. Plus there is a cap off to how much a rising rate helps, its not a linear graph line, fuel pressure increase = more fuel, it starts to taper off to the point of no increase at all.
. . . .
I guess I should have been more specific. 1:1 is a "rising rate" fpr, and I had just noted its a good item for boost.Rising rate regulators main purpose is to offest the boost pressure in the intake tract not to increase the amount of fuel injected at higher boost pressures. If you are running 40psi of boost and have 40psi fuel pressure in your fuel rail even when the injector open there is no pressure differential therefore no way for the fuel to "flow" out of the rail.
