It would be better just to tune to the fuel that's available in your area. Octane boosters barely do anything to raise the octane rating of your fuel and can be highly inconsistent. It's much easier to just tune to what's available without adding any more variables such as octane booster. I honestly think it's just a gimmick anyway.
