    Epa 10 check engine light but no derate. Told the solenoid for BPV is bad. They told me i can tie the wastegate open and will loose some boost performance but not hurt anything. Question is if the little shock looking valve is completely withdrawn into itself would that mean the wastegate is open or closed?
