The dump valves that give the 'sneezing' sound as you put it will be any dump value that vents to atmosphere. Thats the noise you hear. If you buy a re-circulating dump valve that will dump the turbo's air back in to the intake system and you will here nothing. As on a std car.

I think that's yet to be 100% proven either way. I have a Forge v.t.a. dump valve, and I'm very impressed with it. As for fuel ecomony - YES, you'll use more fuel.........but only cos you'll want to take it to full boost to hear the WHOOOSH!
