    H22 fuel pressure

    ...My stock H22A appears to be running a bit rich. I have an adjustable fuel pressure regulator set to 30. Can anyone tell me what the stock fuel pressure should be. Is 30 a bit high...?

    Thanks...

        Did you remove the vacuum line and piug it when you were adjusting the fuel pressure cause if you didn't your getting a false reading

            would this also apply to larger RC injector with spray pattern is optium for 43.5psi? OR it should not matter much and I should set it down to 32/35 psi.
            Right now I run at 40psi at idle and 45psi at WOT but I do have the SAFC II to lean the bigger injector out.
