i just saw today on Horsepower tv as they were testing out their new engine dyno machine a cam they had that switches the firing order with the number 4 and 7 cylinders that they say increase and promote flow. the engine they tested it on had a healthy gain but i just wanted to know if this really works on all engines. How have i never heard of this?
is this relatively new?
can this be used well on a supercharged engine?
