    commanded spark not on targer, shows Torque mangement removing timing.

    I've zeroed out all the torque management tables but I still see up to 4 degrees removed when I run this engine. any ideas?

    this is a stand alone engine swap.

    After a few runs on the dyno I got the spark figured out, I had to increase the Max Torque Timing table, after I adjusted that, the timing on the scanner indicated what I commanded in the tune.

    408 Inch LS 6.0L Iron Block
    STOCK LS3 Heads, Stock LS3 Intake, 92mm throttle body.
    230/236 @.050 114 LSA .595 lift
    534 HP, thought it would have made more, but it is turning the complete accessory drive, water pump, alternator (hooked up and charging)
