My boat requires premium fuel. I keep a few bottles of the 104+ octane booster on board (the black ones), just in case I have to fill up with 89 octane. My boat stays on a trailer, and I try to avoid doing this but, in a pinch it has worked. My engine will "ping" under full load with 89 but with the booster added it seems fine. I guess that each engine combination will be different.

You want to read a little on octane boosters. Most are common chemicals that can be bought much cheaper. Check it out.

Oh I am not a big fan of octane boosters but they will work in a pinch.

I think procharger offers an 89 octane kit. Not sure as its been a while though.
Dont go the booster way it's not worth all the hassle. There are other ways. But more money. 540 x 3.3l whipple x 3 lbs boost = 750-800 hp on 89 octane also = 25K +-
