Bad Timing Dip 1st To 2nd Shift

[TURBOSILVERADO11]

What table needs to be changed to get the big timing pull out of the 1st to 2nd shift? On the rest of the shifts the timing makes a v shape, but on the 1st to 2nd shift it makes a big u shape and kills the truck. I'm not sure if its in the base minimum spark table, or the torque management torque factor. Truck is a turbo cammed 2011 Silverado with a 6l80. Here's a data log of the timing dip. Thanks for the help.

The 6 and 8 speeds alike will calculate the time required to complete a shift under the given time frame for that calculated engine load and if it doesn't see enough time allowed it will do a "super" cut like this. The only person I've ever seen get into the actual's of what defines the shifts is Cringer with his 6 speed tuning vids. He goes by silversurfer77 I think on youtube. His videos cover the transmission side of it. Also I don't recommend getting caught up in the tm debate. Even with tm completely killed if the trans see's something not working it will still cut torque - just use common sense - if you feel it banging in gear, dial it back or if you want to use tm then use it I recommend adjusting what's defining the shift, then adjusting min spark (watch out on adjusting this too) and other tm parameters after the fact.
