When you say better octane what fuel were you running?
Have you tried a 91 and E85 mix?
I have not tuned the older N63 motor yet. The motors are different in a lot of ways as well as the hp ratings but you can expect some very similar results with the older motor as we would do many of the same changes that we did to the ECU programming on the later car.

The Octane was raised with an Octane Booster but the tank was almost empty when we did it so it was quite a bit of Octane Booster compared to the amount of gas. It was dine using the Boostane Professional Octane Booster. I'm not really sure what octane it would have equated to, opinions very widely with octane booster. What I can tell you is that the difference was enormous.
