If the stock boost was bad, by leaking boost, then the Hyperboost
rectified the leak and gave you the boost you should have had
all along. The BPV will not, in any way, give one more boost, unless
there was a leaky BPV to begin with. Maybe the diaphragm in the Bosch was leaking - they're infamous for doing this. My point wasn't to say that the Bosch was better than the piston designs - it was only to show that a BPV wont give a healthy boost circuit more boost
pressure. I'm not sure which particular Bosch valve they use on the
Aero, but I do know that they're usually sufficient for boost pressures
up to about 20 psi on the Viggens or 9000's.
