there'sno doubt they do, but I wonder by how much if i run 0 dump valves. I mean i ain't gonna be doing 50k on that engine/ turbo anycase, but a few thousand might be nice!!!

I would definitley use a DV. The noise you here when you come off the throttle (chatter) is not the wastegate popping, but the turbo stalling. That's giving the turbo a very hard life. You'll also have bit more lag coming back on throttle.

if you are running big boost Chris,which you will be then i would say yes to a dump valve.

if you don't wat the noise the get it to re-circulate.
