    I'm not going to claim to be great with automatic tuning, but have you tried increasing the spread in MPH between up and down shifts? It seems pretty tight at low throttle positions.
    Hsquared racing engines RHS 427, Procharger F2, Moran Billet Atomizer injectors, Alky Control,Mast LS7 heads, Nitrous outlet kit,Tilton quad disc clutch, DSS shaft, RKT56 ZR1 trans, RPM Quaife diff. Built and tuned by yours truly.
