I have a 4L80E with a shift kit. I had someone do a tune on it before I had it rebuilt and Im not sure if the pressure settings or any of the other settings are stock or not. It shifts very hard during upshifts and when I go full throttle and it downshifts. I also do not have a stock tune to compare to anymore. Here is the tune if somebody could take a look at it and let me know. The vehicle is a 2005 Silverado 2500HD 4X4.

Log into your hpt account and go to their tune repository. They have lots of stock tunes

Here is a 2005 Silverado 4L80E stock tune file
Use a compare in VCM editor, looks like there are a lot of differences. Also look to see if torque management has been turned off.
Talk to the transmission builder to see how it got built. I build to suit the engine HP & Torque you tell me you have or are shooting for.
A tuned PCM & a built for xx HP/Torque will create what you described.

I might be blind or maybe they are calling it something else but I do not see it in there anymore.(Disregard)
Found it! wasn't looking in the right place
