What is the role of the Turbo regulation valve?
RIGHT: the turbo regulation valve, a solenoid valve electrically operated that regulates the vacuum force used to control the Wastegate Valve. It connects the Wastegate Valve actuator to either the atmospheric pressure (to lower the turbo pressure) or to the turbo regulation vacuum reservoir (to increase the turbo pressure).
What happens when you reduce the vacuum on a turbo?
Less vacuum = less boost. By modulating the amount of vacuum the turbo actuator gets, the ECU is able to control boost pressure. When the ECU cannot control boost pressure, the actual boost deviates from the specified boost. When this occurs, the ECU reduces fueling and requested boost to ensure that the turbo is not damaged.
How does the Turbo actuator control boost pressure?
By modulating the amount of vacuum the turbo actuator gets, the ECU is able to control boost pressure. When the ECU cannot control boost pressure, the actual boost deviates from the specified boost.
Can a BOV valve open when the throttle is open?
A BOV relies totally on receiving boost pressure from the manifold to stay shut when the throttle is open – if the hose is not connected or suffers a pressure drop for any reason, the valve can open under boost.

Why do I need a BOV in my Turbo?
This dramatically increases the load on the bearings of the turbo. If it occurs at higher engine loads and/or boost levels it can cause premature wear to your turbo. To sum up, a BOV prevents turbo flutter by venting the air pressure that causes surge.
What causes turbo boost to mis-adjust VNT actuator?
air an appropriate adaptor (s) and a regulator. Cause #2 mis-adjusted VNT actuator. The VNT actuator is the device on the turbo that has a vacuum hose attached to it. It is sort of ball or can shaped, and has a rod sticking out of it. The computer coding is written around a specific rod length.
