The only good idea was adjusting PE to come in sooner and faster. The rest of the changes should be discarded.

Discard like the high and low spark tables and how did the transmission tuning look?

It looks like you copied settings from another vehicle. It's bad.

I would start with this. You will need to adjust your shift points and tcc lockup, i just made a best guess on what may be comfortable. Get a log.
