This is exactly what i'm talking about. Would a atmospheric dump valve be any better?
I seem to remember when i spoke to Si about getting one for the kit he told me HKS don't recommend fitting the SSQV........(unless i'm remembering that incorrect, Si please correct me if i'm wrong)

The issue is less down to choice of vent to atmosphere or recirc but more down to size of bypass valve and whether it can flow enough air when required.
There are lots of posts about the SOS style kits having issues with undersized bypass valves and people opting to weld in new flanges etc. The problem with the HKS kit is that you would have to get some work done to get a different valve to fit or replace the pipework completely like i have done.

It would seem at least three of us from the HKS group buy have the same symptoms. Would this hint that there could be an issue with the valves in a manufacturing batch?

I can attest to that! My TTS came with an atmospheric BOV and I've been considering swapping it out for a recirc due to the noise. For info, that one only chatters/flutters when really gunning it (above 6krpm at full throttle, then closing the throttle). The rest of the time it just hisses.

I have spoken to HKS - they are having a read of this thread and going to speak to me soon!

That's correct - they confirmed they do not need a SSQV - the type of recirculative kit that comes with the charger is fine and fitting a universal SSQV is more detrimental to the performance of the setup.
