If I'm running 93 octane on the 93 setting theres no use in messing with the timing is there?

I don't think there's a 93 octane tune, but there IS a 91+ octane tune (which tries to be a catchall for anything at or above the 91 octane level. If you use 93 octane gas, I'd try setting the timing to +1 degree (0.5 degrees for each octane point above the tune level). With the engine all warmed up, "stand" on it and listen for ping. If you hear any, back off.

Oh, and Bill would do some other things to optimize your use of 93 octane juice over what YOU can do!
