GT500 Elliptical Throttle tuning

I had this throttle running good a while back, HPT updated some of their idle controls on this particular model, 2014 year, Copperhead ecu, and I changed to a smaller blower pulley. Now, I can get it to go into idle control of ignition and throttle, and it runs good, idles pretty smooth, but right before it goes into idle mode, it pulls timing way down to where it almost dies, like stopping at a light.
I can not figure out what controls the timing while in torque control mode. I used to think it was by the torque tables, but I can't get them to not lower timing so much, after the pulley swap. Car has cams, and I think that makes the ign timing control worse, since the ecu thinks the engine is decelerating when the rpms vary from the cams loping. Anyone ever had this issue? Tune attached
