The only issue with that setup is that while you can have a significantly wider range of boost control, the resolution goes down (i.e. a slight change in duty cycle can greatly affect the boost level). I personally think electronic actuators like many of the German OEMs use and what Infiniti/Nissan use on the VR30DDTT is the best way to go.
