Unless the pressure limit is keeping the pump from running wide open against whatever mech reg is in the pump setup? Basically some of the factory tunes arent running the pumps wide open at full demand? Can you watch actual pump current/duty?On the other hand, this couldnt be used say in a scenario where you put 2000cc inj in a car, and wanted to set the pressure to 30 psi to allow the pump to flow more volume at that pressure, and your way oversized injectors can still deliver enough flow - can it? Not sure how computer could make pump run 30 psi without taking power away from pump. We done that in some pump limited setups, drop fuel pressure to let pump eek by, and put lot bigger injector in it
To access this, is it $50, or $50 per car or?
