REMEMBER the boost is pushing against the fuel back into the injector, like 20 psi off the rail pressure with a pulley kit. You can run the engine without the fuel pump on idle as the suction will draw fuel from the injector body. Been there done that. The adjustable regulator just adds boost signal to the regulator as you increase the boost - DYNAMICALLY as you drive.. High rail pressure would flood the motor if it were set up all the time, ie my 9:1. Its all about effective injector pressure:: Rail pressure minus the boost pressure= effective fuel pressure
