Octane correlates to dynamic compression. The more boost, the more octane you need. At ~12psi (stock level) you will not notice a difference with high octane fuel.

I noticed an improvement of about .1 second in the quarter...not much better with like 1 or 2 mph faster...that was stock...not worth the 10 bucks to add 2 gallons of gas...
