i have a bonestock jdm b16a in my 92 cx, i'm using my cx stock fuel pump and i'm at 40 psi right now. should i adjust my fuel pressuse regulator to a higher psi? how do i know if i'm running lean or rich? by the way i'm using an ericks racing p28 ecu

45 psi what where you running stock?

stockegsix

i was running 38 psi, i just looked at my spark plugs today and realize i wasnt running rich. but lean. i raised the pressure to 44 psi and notice my car ran a little better than before. i'm going to raise it up higher maybe 48-50 psi and see what happens.

I was running 40 psi w/ stock cams.

Did ITR intake and Cams made a big difference?

Are these pressures with vac line on or off?

I ran 50 psi with a JUN type 3 setup on my old 99Si with Hondata ecu.
