    Start with some basics:

    Main power and ground should be directly to the battery.

    What ignition system is this used with?

    Return style or PWM?

    Automatic or Manual trans?

    Target idle?

    MAP value key on engine off?

    i am now thinking it is my map it is reading 26.8 hg when it should read 30.1 hg according to local weather or is this not a big enough of a variant to be concerned about
