It was a little loud so I added a filter and wrapped the filter with foam and that setup works very well. It has never stuck and would highly recommend. Does not flutter for me either, where as all the others have.
I've also used the Synapse valves, both old style & new. I've spent a small fortune trying to fix the flutter issue.
QRJ ftw!! Stage 1.5 setup.
