Fully agree and admittedly my comment was more for giggles, but car’s not stock; previous owner upgraded turbos and doesn’t know anything about the tune. I don’t know anyone who can tune an obd1 system so after I get the clutch done my next big project is rewiring with a post-1996 electrical system.
Eh. I’ve never owned a car that required “premium” fuel but modern engines are completely capable of adjusting ignition timing as necessary. You’ll just make less power.
Use whatever the manufacturer reccommends. If they don’t reccommend premium, you don’t need premium.
Don’t be scared, be knowledgeable.

Have you looked into a standalone system like Holley or similar? Seems like they make it easy now at least from the YouTube videos I’ve seen 😅

Is 1991 modern?
No?
