I really like the idea of being able to throw 91 in it when I want to take it out and get it dirty, just to have a few more ponies to play with.

As far as choosing octane goes, I run Sunoco in my supercharged Mustang at the track even though it's only canned-tuned for 91 because I like the little bit of extra "cushion" it gives preventing detonation when I'm hot-lapping. Sure, I'm not using all that octane for more power and I know I could probably get better timeslips by running the fuel it's tuned for, but until I get it on a dyno this spring for a real tune, I use higher octane fuel as my crutch.

I wish 89 was cheaper then 87everywhere. Welcome to the boards!!
