Hi,
I am new to the forum and just purchased a 2020 ST. I live in Colorado where 91 is the highest available at the pump, so I am looking into E30 or E50 tunes. Now from what I understand, those tunes are referencing a specific ethanol percentage, and I am assuming the standard blend is with 93 & E85. So if someone was looking to get similar performance to those tunes with a 91/E85 blend, would the mixtures need to have a higher content of E85? Hopefully that makes sense, but basically are we looking for a specific ethanol content or an octane rating?
