There is no slipping whatsoever in the climb through the powerband and when the shift happens, its solid with no apparent slippage or slush.
It's obviously being delayed within the transmission but when it does happen, it feels healthy.
So, I don't think I have any clutch slippage issues.

I did some research and found this thread which further helps me understand things. Look at line 5 about shift timing.
I think Ill try adjusting the the max MpH lower to see if that gets me where I want.

Also, further down in that post look at line 3 in the tuning suggestions
I compared those suggestions with my bin and I think I found another potential issue with my bin. I posted the table below.
The tuner (who I'm sorry I paid) has errors there too I think.
In the 2-3 shift timing its set to 6.38 seconds.
Shouldn't that be .638 sec instead?

NEVER used a shift time higher than .750.
6.375 is the shift time for T56 .bins.
