BOV or no BOV w/ECU 850

The high pressure turbos have a blow off valve / bypass valve
already. These help keep the turbo spinning when you back off
the throttle (so it is ready when you get back on). The Volvo
design vents back to the intake side of the turbo instead of
venting to the atmosphere. I would not think it would make
much difference for the boost values you are seeing unless you
are lifting off the throttle then getting back on.
