Ok, i just got a SARD Type R Adjustable Fuel Pressure Regulator. I am running stock injectors and stock fuel rails, but i have modded the rails to run in parrellel rather than series. ( I doubt that makes a difference) I am running 5 psi on a Legacy Turbo setup. What should my IDLE fuel pressure be, and what should my On boost Fuel Pressure be? I have two gauges, one reads PSI, and one reads a weird metric reading. I just want a breif summary of what pressure i should be looking for!
