Here's the real point that it would seem everyone is missing.

In any event, it's a ridiculous claim and utterly w/o technical merit.
It's not going to by you ANY horsepower on a motor that isn't currently pinging. Octane does NOT add power (in fact, the higher octance fuels have a specific energy that is approaching 0.5% LESS.

The ONLY way it can add any power is on a motor with knock control (many many modern car motors, but as far as I know, only on HDs in the motorcycle world) On such a motor, the basic ignition timing and compression are pretty aggresive. The ECU looks for any sign of knock and retards as appropriate/required. Just dumping higher octane gas in will not buy you a single horsepower. You're far more likely to lose 1/4 horse.

p.s.
you could advance your timing a bit, or bump up your compression ratio, or have a chip custom mapped. Those would all help when used with this gas, but by itself...nothing
