It wont make it slower and will make more power. your car can make more power depending on the brand of super you put in it also.
THE ECU WILL NOT ADVANCE TIMING TO TAKE ADVANTAGE OF HIGHER OCTANE. Timing advance will follow the ignition tables unless it makes corrections or it triggers a setpoint for a correction factor table(namely CATs.) That means that if you're having timing corrections and you mix in 100 octane then it will just clear up the corrections.
