Unless it's called a Tornado, then according to a dyno guy in Red Deer (Dr. Ligthspeed?) then it does work. :confused: It doesn't make sense to me that it should work, but whatever. My guess is that the disrupted air through the airflow sensor tricks the engine to run leaner resulting in more power and better fuel economy, but who knows.
