I just bought one of those adjustable fuel pressure regulators and want to mess with the fuel pressure a little bit, but I need to know what the pressure is supposed to be from the fatory. I don't have one of those manual yet. Any info is greatly appreciated. Also, for those people who are running adjustable FPR's at what pressure do you find the best power increase or does it really matter what kind of mods you have done to determine that spec? Thanks in advance, Paul Moore

how, and where did you install it?

anyways, the stock LS1 fuel pressure should be 58 psi, static (non vacuum referenced)

So if your car is reading 30 psi, it will not run worth a **** right? Or how will it run?

At some point it would run lean....the ip would increase until you ran out of injector.
