If im running 38lb inj, 255 pump, and a SAFC II on 5-7psi max boost do i need an SFMU or will the SAFC II be able to curve the fuel flow enough?

I have an SFMU lying around but never decided to install it because way back one member said it would be overkill for my set up. Is this the general concensus? I dont want to waste my time if its not needed at the moment. I dont race, its just a daily driver car.

Further, im not sure of my FP levels yet but is the SFMU pretty much the only way im going to be able to lower FP levels once I do have a guage to read the numbers?
