Re: More Fuel!
Injectors are normally rated at 43.5 psi also. So, when the 1G runs 36-39psi stock, you aren't getting the full rated capacity of the injectors. If you run 550s at a base pressure of 52psi, then they will act like 600cc injectors. I like to try to keep the base pressure + boost pressure under 85psi. When you turn up the base pressure though, it is harder on the fuel pump. So, if you are running out of fuel pump, but not injector, then you might want to actually try lowering your base pressure to get more flow out of the pump.
