Default What octane are you running on?
I put 94 octane when available, if not- I'll put 91-92 octane. Alot of people say it is not worth the extra$$$. I find the car does run better though- maybe it is all in my head?? What is everyone else using?

87, but when everything is over 3 dollars a gallon bumping up the timing is not worth it.

93 with 13 degrees of timing. Cant really go too much lower. Next lowest around here is 89 which is too big of a jump.
