    Hi all just acquired my HPtuners MPVI3 and am trying to tune my cammed 2008 5.7Hemi in an 70 Cuda
    I am idling reasonably ok in P/N, but sometimes hunting for idle (mostly happens when reaching running temperature)

    Exhaust Duration at .050 Inch Lift 228
    Intake Valve Lift 0.547
    Exhaust Valve Lift 0.55
    Lobe Lift Intake 0.342
    Lobe Lift Exhaust 0.346

    I might start with Min Air Flow table in the bottom three columns. Either Add or subtract and see if that helps.
