Adjustable Fuel Pressure Regulator
What are the pressure of the factory regulator on a GTR?
How much pressure should an adjustable pres. regulator set to? I remember someone saying that you should set the pressure regulator with the vacuum hose unplug??? What will happen if I set it too high or too low?

If you lift your base fuel pressure you will flood the engine at low to mid RPM's unless you have an adjustable ECU or interceptor fitted, in which case lifting fuel pressure is a good way of squeezing a few more HP out of your standard injectors.

A cheap way to increase fuel pressure is to simply restrict the return more then the regulator already does. Install a restrictor, crimp a line. Take your pick...
