No DV/BOV makes that fookin noise.
HKS BOVs make a ptchhh like all others.
Only reason people think they make chatter noise is cause they generally replace the recirc ones, and have MUCH stronger springs than the recirc ones (to stop the cars stalling cause AFMs and vent to atmo BOVs/DVs dont mix), so dont open as far or as long (esp at lower boost levels) so it makes the car chatter a bit too...
And yea Tony, any petrol turbo can chatter, dont matter where it from
I got a couple of incar vids of a R34 on track with REALLY silly loud chatter.
