Thread: Check valve / pressure regulator to tune boost bypass actuator/solenoid?

Questions:

- Did I describe the operation of the boost control actuator and solenoid correctly? It that basically how the system works?

- Is it possible under some load conditions for the vacuum line from the lower intake manifold to provide BOOST through the solenoid, pushing the actuator toward opening the bypass valve? Perhaps more so with a smaller pulley?

Regardless whether or not I "touch it" I'd like to understand the system better.

Along these same lines, can the operating parameters of the BCS be tuned in the ECM? Maybe to tune launch characteristics?
