    Just off the top
    Of my head, cruise is like 14.7 and exceleration drops to like 11.5-12 with JCW injectors. I'll get the fine details during the week for ya.

    Do any of you know what inj size you are running?? And at what rev limit do they 'max' out, if they do?? I am running the OEM 330's at present.

    Thanks

    Mine reads nothing, because it started lying to me and I took it off of the car. It might have been a cooked sensor, don't know.
