90 Ethanol Free gas and Tune question

A newer gas station by my work has 90 Ethanol free. I am currently running 93 gas with a BAMA Race 93 tune. (lets leave the tune bashing and arguments out please). My question is would 90 ethanol free be better and cleaner than 93 with ethanol? I mean it is less octane so I tend to thin k the 93 better but no ethanol is a good thing right? It is $3.79 for 93 (dropped allot last couple weeks) and $3.85 for the 90 E-Free. Anyone have input on this? Also I am assuming a different tune would be required as well.

There is a lot of information on the benefits of E0, but I have never heard anything about a tune. When I was willing to test Bama tunes, they said they could account for 89 E0 (the gas I have been using for over a year from the same pump at the same station lol)

Talk to Bama.

I have no ethanol 93 from a Conoco up the street. Justin at VMP created my tune based off of octane and ethanol amounts in the gas I use. Fyi
