not trying to clown on anyone setup or question all the v12 gurus lol just trying to reason
If your wanting to maximize the sound of the blow off then definitely fix the factory diverters closed and just plumb in your aftermarket Bov's of choice. And your correct the diverters don't have anything to do with building boost and or maintaining boost in proper working order, it's the wastegates.

pretty much that is what I want most sound if I am adding after market vent to atmos BOVs

i am going to hook up a mechanical VAC / BOOST gauge on the lines that go to the stock diverter valves to see whats going on at acceleration and lift off and post the findings.

I knew what you meant, tho it's not a WRX... And sounds perfect, anymore would take away from the Benz status imop.. Lastly T splicing into oem lines right in front of coolers is 5 min work etc..

What you will see is the diverters get boost pressure whenever the ECU is commanding boost through the change over valve. And when the ECU wants boost cut/no boost situation due to off throttle, limp mode, etc. it will be atmospheric pressure or vacuum, I cant recall at the moment if the switch over valve also has vacuum plumbed to it, but I don't think so.

thank you sir. that is what i was thinking is there any time delay or is it pretty instant from boost to vacuum?

now does that line get the same same boost pressure as the car is making or less as per some derived formula since it is going through to diverter valve solenoid.
