Then how is it that I made significantly more power on e85? I think there is just a lot of misinformation out there on it. People get great results with it and if you have a tuner who knows it, they can get you safe results.

e85 is the reason I'm upgrading my clutch. 93oct @20psi no problem. e85 @16psi and the clutch starts giving up. This was on the same day, back to back tuning. My high boost tune is waiting. :)

We tuned my car with class3 in the tank vs doing it in the summer when class1 is available. We didnt try to guess at detuning. It runs safe and will do so as the classes change with warmer weather. I test at the pump and mostly run 93oct during the work week.

Octane ratings are often debated, so let me copy from a decent source- VP fuels sourced for info
91 r+m/2
93 r+m/2
e100 122 r+m/2
e85 117 r+m/2
e70 111 r+m/2
q16 118 r+m/2
c16 117 r+m/2
VP import 120 r+m/2
