Car was previously supercharged...didn't have stock injector clips for stock injectors. Engine code came back as running too rich or lean. I know I'm running too rich that's why my light came on.

Only part on car now is 255lph fuel pump, FPR, headers, exhaust...still have check engine light. Adjusted fuel pressure to about 32....What does the stock fuel pressure regulator pushes out? I need to know so that I can pass emissions.
