The logs look okay.

It sounds like you are looking to add a little e85, a lot of our users add e85 when using the pump flash- blends up to around e30/40 are usually okay. However that all depends on the health of your HPFP / LPFP- those weaknesses aren’t usually shown until you try adding a bit.

I’d start by adding 2-3 gallons of e, and monitor your fuel pressure, AFR & Timing

Also- enable 6cyl logging under user adjustments for your next round of logs & we have updated firmware if you are so inclined
