    Attached are a few screen shots of information I use from TunerPro RT to tune a chip. These pics are from a "tune in progress". The vehicle is a 1992 K1500 with a performance TPI 305, roller cam, Trick Flow Heads, Cold Air Intake, with long tube headers flowing into 2 1/4" dual exhaust.

    Knock Retard is not good.

    VE fuel is close.

    A few more TunerPro RT data logs needed.
