I sold the setup and moved to ESS and couldn't have been happier. Many have spoken about the ESS system and how it feels like a stock setup and I would personally support that claim from my own experience. In addition to the noise, there were other factors that had me favour the ESS over the AA, but we will leave those items out as you wanted feedback on the BOV.

Best of luck with your decision.
Curious, do you have MT or DCT?
This was on a previous car which was a manual.
