Update: I picked up a SHP Ninja reg and placed it on a used 45/4500 that I was getting hydro'd. Output is well over 1200psi (limit of my reg tester). Of course, with the screw all the way counterclockwise, I can't get under 305. I may try to remove a shim or two here. Any other ideas? I say Ty post somewhere else about the sweet spot being 925-950...
