I’d probably be more concerned with blowing the motor on poor quality fuel than anything else. There was some guy on here who damaged his motor on ACN 91 on a stock car. Although as long as the knock tables are not modified, it shouldn’t be much of an issue.
You’ll be surprised how much timing gets pulled on just a stock map on 91/93 octane.
I’d feel safer running a low boost ethanol map with an ethanol meter just for the peace of mind that octane wouldn’t be an issue.
