My big end this year was 17-18 mph compared to 20-21 mph last year. That'* not the same.
5 mph is significant.
Last year was with a 3.0 pulley and Gen3 and this year was 3.2 pulley and GenV.
The WOT A/F mixture shows on my wideband as 10.9:1 and I don't see any KR with WOT timing at 19*

Your right I was looking at the wrong side of the slip. Are you still running stock injectors? Have you scanned injectors duty cycle?

If I manually downshift, I do not get KR.
If I punch it from 30 mph and it downshifts, I get KR...
WOT from a stop, I get NO KR.
I have an Aeroforce gauge. What do I look for to determin duty cycle? What should it be?

Check your Injector Pulse Widths. Duty cycle is a forumla of rpm vs pulswidth and can be calculated as
rpm times IPW divided by 1200 equals IDC in percent
so 6000rpm and 22 ms pulsewidths would be ((6000 * 22) / 1200) or 110%
