SPO1715,
So that ratio of 3 @ 111 and 10 @ 91 yields a 95.6 octane. That works best for you? What compression is your engine?
When you used straight 111, you said it ran like crap at the top end; what is your top end defined as? At RPMs above a certain level? Or MPH above a certain level?

How did it run at the low end?
