Based on WOT fuel trims I suspect you're running E10 93, which means you're trying to add 5 deg timing on top of what Ford was running when the stock tune even runs into knock on 93.
You have to get your fuel trims nailed down before even considering trying a flex tune. It should learn 10% ethanol on gasoline, not 30%. And your borderline timing modifier for flex is way too much. How did you arrive at adding 20 deg? And how did you arrive at populating all the MBT tables with 33 deg?
And besides, HPT is lacking a few very important parameters to make factory flex work...namely fuel line volumes. It will mature too soon after a fillup and will be inaccurate when switching fuels if you don't correct the fuel line volumes.
And where are you getting 21 deg from? Your data rate is so bad it is hard to tell what's going on with the timing but in both the logs posted above it's hitting a minimum of 24 which about as good as it gets on a Gen3 on 93.
We can talk timing logic if you want but you really need to understand how it works before drawing the conclusion that it's bad, good, or otherwise interpretting the data.
