Just fyi the duty cycle is whats being commanded and not necissarilly what the turbo is doing. The computer could ask for 85% and only get 50% for instance if the vains are sticking. Also the duty cycle at wot is 35% I believe. The lower the number the vains are open and the higher the number the vains are closed to act as a smaller turbo which makes the hair dryer sound or whistle on the pmax. I believe the highest it will ever go is 85% and the lowest 35% but not sure on the lowest. I know it cant open all the way(lower number) or you would have vain and turbine blade contact as they would open into each other. As I said not sure on the lower number being 35% as the lowest.
