I can't tell from your post if you really boosted your octane or just added some of the usual over-the-counter stuff. In any case, boosting octane alone does not result in an increase in engine torque or power. What it does is allow you to tune the engine more aggressively (e.g., more timing advance) without suffering detonation. So, if you don't retune the engine after you raise the octane, you won't feel much difference. .. Unless you have a computer controlled fuel injection that automatically senses and adjusts for the fuel.
