More power with higher octane same tune?
most people run race gas and add timing or boost which adds power
All 91 octane fuels etc are not the same ? Octane is only one aspect.
But pump gas can vary load by load, you have specific gravity, flash points, all kinds of things that come into play. Not to mention 'exotic' chemicals you can pour in there to make more power without raising octane but wouldnt pass a fuel check at a racing event. But just raising octane (anti-knock) doesnt increase power on its own.
