BOV, Recirculation valve M278
Saw a couple older threads with good info. Just wondering if anyone is running either these days. I'm looking at a Tial recirc valve. Wanting to install this along with the catless Red Star downpipes, UPD intake risers and Renntech HHT tune. I'm looking to plumb the boost bleed back into the driver airbox, as the valve itself will be installed on the passenger charge pipe.
Any recent info/stories/experience?

Depends on the weather
No experience with it on the S550 specifically but I installed one on my vette. I had the Q first but it was too quiet and changed to the QR.
Weistec has them for my M275 and so you may want to check to see if they hae them for the M278.
