Octane more than required by designed will produce very little noticeable power gains. You may get a little because the PCM will add a little more spark advance if your car would have pre detonation in the cylinder and is being adjusted back through the knock sensor. Probably not noticeable. My 2001 knocks like crazy and doesn't have a knock sensor. Regular gas on a hot day' pings like crazy and I can feel the power loss under load but that is an extreme case.
