the obvious question for me is for the big turbo A4 owners...is something like these BOV's going to be a good idea with a T28 or GT25 turbo'd A4 which is producing 23+psi peak, and spiking up to perhaps 26psi?

The idea that the valves remain partially open at idle was like a light-bulb going off in my head. Makes me think that the hi-boost shredding of many BPV we see here would be negated by the atmo bleed.

Cheers,
Sameer
