gear hang up

I have a 15 2500 with 4:88 gears, whipple supercharger, 1000cc injectors, dsx e85 sensor. Mostly in 3rd gear I am getting a 3krpm bounce and hang up. Cant figure this out. I attached log files and my ecm setup. I changed the trans tcc desired slip to zero and helped with normal driving and shift timing at a loss with this.
