Quote: I see they are running dual waste gates on this setup. Is that needed?
What is better wastegate or BOV? and why?
A BOV serves a different purpose. It dumps boost when you get off the throttle. When the throttle blade closes, the pressure spike is far greater than boost pressure and puts a lot of load on the compressor. The make some large gates that can handle a lot of flow and don't think you would need two gates.
