Thanks for the reply @
corksil, kinda bringing this one back from the dead. I've put a couple hundred miles on it now since the swap, freeway riding and all, and I would definitely suggest doing it if you're already considering it. It's my understanding that the higher octane gas helps prevent predetonation/pinging and I don't believe I've had any using the 93 so far, assuming it's something I would be able to hear/feel.
