According to the calculator you linked I should be mixing 9 gallons of 91 & 5 gallons of E85 to get 36.5%. (I'd like to run 5% higher ethanol content as a buffer).

If you run more ethanol, you can use ATR to adjust the fuel scalar accordingly and get your trims as close to zero as possible (there's also a table in the tuning guide for mixing ratio to fuel scalar value). Just continue to log and make sure long/short term trims are good. Enjoy the extra power at an affordable price
