One Wastegate or Two?

Building a 6.0 with a VS Racing Billet S480. I have a Tial 50mm BOV but someone recommended I run two waste gates to make sure the boost was steady. Any input on this would be appreciated as I am about to start piping. If two is better what size would be best?

What is your minimum boost goal and how will it be plumbed? I'm doing an s480/6.0 right now and I think I can get down to 8 lbs or so with the mvr 44 china copy.

I had a divided 2.5" hotside with a s480 on a 6.0 i was running a single jgs50mm gate and could control down to 5psi no problems. I just made a nice y setup into the flow right at the turbo. Best to make the flow going toward the gate for best control. If the exhaust doesnt flow toward the gate the pressure will bypass it and youll have boost creep issues. But non the less a single 50mm gate will work!
