Hoping it's not the BPC...

One thing that perhaps you can clarify: I was under the impression (but don't know now where I read it) that rather than the ECU telling the valve what to do hundreds of times per second, it actually presents a pulse-width modulated signal to the solenoid at around 12Hz (12 pulses per second). This seems to me to be more achievable with such a clunky electromechanical device. Perhaps the ECU calculates how it wants the boost hundreds of times per second, but I would have thought the BPC valve incapable of following these calculations at such a rate. The response of the turbocharger is probably even slower than that of the valve.
Just my opinion and something I read somewhere once.
