Maximum smoke at full thrttle can create enough backpressure to reduce power by over 30%. The oil expanding presurizes the muffler more than the exhaust gases leaving the combustion chamber.

Even the setting for max moke at 50% throttle will give a noticeable power loss. Its tollerable at that level. If you are used to being able to do torque rolls and set for max smoke at full throttle... you will not be able to torque roll at full throttle.
