TurboXS Hybrid BOV
The BOV itself is well made, was easy to install, and functions as intended. It's responsive, and if you're worried about being rich between shifts, it's unperceivable in datalogs, and I haven't had any drivability issues.
There are instructions on TurboXS's website, but they could be better. The BOV appears adjustable in preload by turning the valve body clockwise or counterclockwise.
I'm not sure how to describe the sound profile because that may depend on your intake and turbo setup. I am running a larger than stock turbo and a large intake, so the sound I get is not a distinctive "whoosh". YMMV!
