93 vs 91 octane: how much difference on the dyno?

Just curious how much the difference would be on the dyno with say a 11:1 compression?

Unless your having detonation problems with 11:1 CR and the 91 octane (witch I very highly doubt) then you will have very little to no difference in power. If there was a difference in power on the dyno between runs it would probably be within the dyno's margine of error.

Probably very little, anyways you should dyno with the fuel you run most often in your car.

I ask because when my car was dyno tuned it was with 93 octane gas. Unfortunately 91 is highest we get here in CA so I was wondering if there'd be a difference. Well, I'll know soon enough though once I dyno it again later.
