Little advice please TCI triple disc

[1slow1500]

Truck is my 2016 sierra 1500 5.3 with 6l80e
it has on3 turbo
stage3 Circle D trans.
TCI billet 2 piece 3000 stall
build then stored away long time. 13,000miles on it now

Engine tune is perfect but the trans I have tried many things. Hard to balance full race aggressive shifts over no boost easy drive. I believe i was overly worried about slip and was way aggressive. So flashed stock tune now on simple slow driving the stall is loud idle to a roll. I assume it is the 3 disc slipping. I have used the bluecat software. and it is good but looking for more input or tips if any. How to videos have tuners say fake the numbers in bc to get the trans to work. like tire size and such.

Think I may just up pressure little and up the shift speeds.> because the stall hates the 3 shifts the 3-1 just to move up in the turn lane.

Note I need to reset the trans (special tools) also as I change tune but first drive it shifts HARD. Still trying to understand that!

Thanks for the help.
