Well a lot is going on, you have desired load below your actual load and this is already bad. Your torque fights with trans truncation
this alone could be the culprit. Next is the anticlunk with indicated bad SD settings. This alone should fix few things but you still need
to extrapolate the TQ model to keep a proper desired load. Dont set you main AFR to 14.7 as petrol has min 5% of ethanol those days.
Log TB angle source, might be still something up with your TB settings. No time for more digging.
