I'm running one of these with a 2035 pump. Fuel pressure is lower when using the potentiometer. The car runs fine, but how can I know what the lowest/safest setting on the dial would be to drive the car? Would I need to adjust fuel pressure when running in race mode? At idle I see a 5 psi drop in fuel pressure when switching from race to street mode. I guess the question is, how can I know if the fuel pump is keeping up when in street mode? Do I have to flip the switch everytime I go WOT? Or is race mode more like a fail safe?
