Great feedback, Bill. Obviously the motor is burning the fuel more efficiently now - do you think we'll see a lessening in the carboning of the exhaust valve?

The tuner of the engine isn't fighting preignition that is caused by the glow plug by running a richer mixture. Spark allows you to lean the mixture far more than a hot glow plug that needs to be quenched in order to prevent preignition.
