My car is 2000 Civic Si. I had a shop to put the Jackson Racing Superchager, part # 989-250, 3 years ago. Last week, I somehow messed with the fuel pressure regulator. I don't know the spec. fuel pressure, and I've lost all the instruction. Please tell me the spec. fuel pressure so I can ask my friend to set it back to the spec. Thanks for the help.

 

Did you ever get the car tunned? if so call your tunner...if not then i would assume it was set to stock wich is about 42psi
