Default I didn't notice any difference with Sunoco 94 over Sunoco 93....

...with my GIAC "X" chip. Try it and decide for yourself.

Only time I buy 94 is when it's the same price as 93...local gas station special time to time.

I can't tell the difference, and I've tried several times.

Default I buy it, but I don't detect the difference with my butt-dyno, nor would I expect to.

But I do buy the theory that it helps - the ECU is designed to advance the timing to take advantage of it. If 100 is "way better" than 91, then the difference between 94 and 93 should be 11% of "way better". :-)
