2008 6L80e high power 2-3 WOt shift

[MoBoost]

2008 Denali AWD
388 / 88mm E85 1000whp+/-
6L80e with best parts
Can't make 2-3 shift at wot. All other gears are fine. I can't get shift to start early enough. No matter what I do the shift doesn't start till 5500rpm but I need it to start the shift at 5000 to happen by 6500. It seems like a hard wot limiter for lowest rpm.

1. Has anyone experienced this with 08s and solved it

2. Can I put 2010 valve body/TCM in or the PCM will freak out?

Have you considered posting a tune and log so that people can help?

Shift MPH and RPM must be met to shift. Check part throttle tables to make sure the 100% column matches your WOT stuff. You must lead the shift by a few hundred RPM.
