I considered this fuel then decided race gas(unleaded 101)is easier to tune...

The E85 is actually easier to tune because E85 is less sensitive to the absolutely correct A/F ratio, it will give max power over a bigger A/F ratio span than gasoline...and the octane is higher than 101 race gas...

Sounds ok but no stations near by and I drive 2-3 miles and fill er up............SIMPLE. The VP-101 I use likes rich tunes as in 12.0-12.2 so far but was as high as 13.0 when I stomped the Vette.............
