Currently, I have a LS6 CTS-V with H/C/I. The fuel system: 42lb injectors + a Walboro 255 in the tank. With the 255 and the in-tank "returnless" fuel pressure regulator, I was running 70psi (too much) so I removed it and run a return style fuel system with an adjustable FPR.

I just picked up a Magnuson MP112 supercharger kit with the 60lb injectors and a boost-a-pump. My question is if I need to go back to a returnless fuel system for the b-a-p to work as it should. I think so... but if I remove the adjustable FPR, I'll have no pressure regulation at all since I removed the in-tank pressure regulator. Go returnless + one of those Corvette self-regulated fuel filters?

Thanks in advance!

If it were me, I think I would leave the regulator. Is it one that senses boost? It has been years since I have set anything up though, but I don't see why you should pull it. If it senses boost, then you can set your base fp at stock, if it doesn't, then I would set it higher.

yes, the FPR is referenced (connects to the back of the intake) I wonder if I need the b-a-p at all?

Put in a 450lph pump.... don't mess around with the Boost-A-Pump band aid.

Keep the boost referenced FPR. Maybe add some methanol injection so you can run some real timing.
