The higher the fuels octane rating, the greater the fuel’s resistance to engine knock. The higher octane takes a higher temperature and pressure to cause it to burn by itself. This resistance to know allows us to advance the ignition timing of your engine to an optimal level, which increases horsepower and torque.
When switching from an 87 octane tune to a 93 octane tune you can expect to see an increase of 10 or more horsepower on top of the gains you are already getting from an 87 octane Bama tune.
When switching from a 91 octane tune to a 93 octane tune you can expect to see an increase of 5 to 6 more horsepower on top of the gains you are already getting from an 87 octane Bama tune.
