As you know they change the cam, tune the ports and increase the compression with different pistons, ceramic coating etc. The benefit is increased horsepower (400 HP) and a smoother engine. I wonder if anyone has an opinion as to the value of this mod and whether it hurts reliability. Also I wonder if the increased HP really does any good since in cruise we fly at 65% anyway? Any thoughts?
