I agree. I wouldn't know where the benefit would stop as in what overall octane number. There's a point on engines where more advance will not make any more power due to negative work from the crank angle peak pressure will arrive (too soon). The pcm does adapt at WOT and does try to advance timing. So, it's possible, like stock, to make more power up to the programmed limit in the pcm using higher octane fuel. That's my basic understanding from speaking with a pro racer package self tuner to get some insight.
