I know this is an age-old question that's been talked about for many moons. I have always been taught that 43psi With the vacuum line off is where it's at. That's what i've always set my fuel regulator pressure to. I installed my new deatchwerks fuel pump255lph ,my injectors are 42 lb. My regulator and gauge are racetronix . The gauge is a fuel rail gauge. I have spoke to a few old timers in the turbo buick community that says 45psi with vacuum line off won't hurt anything and might be better, fat and happy. However i'm a firm believer of doing it the right way and making sure everything is how it should be. What are you guys suggesting on pressures?
