The extra 3-4 octane would serve as a knock buffer.
Perhaps it's all mental, but the car is accelerating super smooth now. You know how in stock form these things kind of hesitate in small spots under WOT? I guess it's been explained as thye go in and out of closed loop. Well, it doesn't do it anymore. Turbo lag in the low RPM's is reduced. It is pulling hard even in high gear. I don't know. Maybe I'm nuts.
