Unleaded higher octane race fuel are great; if you are tuned for it & especially if you’re boosted..otherwise you’re wasting your bucks.
I did intentionally run ethanol free 93octane in mine & occasionally splashed some C10 in with it.....but its a fast burn fuel.
That can open another conversation/ as I’ve ran blended various race fuels with my 93 & would notice how rich it would burn (specific gravity over .800).and sometimes have some build up/residue on rear bumper cover afterwards.
Some additives/boosters are corrosive as well.
I see a lot of good results from “Ignite Race Fuels” (ethanol)....be sure & have your car tuned with it & a specific map setting for optimum results....as Mr. Bsmokes has done.
My biggest noticeable changes came from driving in cold/dense air.
