Not necessarily. There are more BTU's of energy in a lower octane fuel than in a higher octane fuel.
Also the ignition timing is not only controlled by the 'knock sensors" but also by Engine temperature, manifold pressure, throtle position etc.. So using a "dashhawk" or other devices does not tell the whole story.
