Purpose and Benefit for install BOVs:

Blowoff valves are used to prevent compressor surge.
Compressor surge is a phenomenon that occurs when lifting off the throttle of a turbocharged car (with a non-existent or faulty bypass valve). When the throttle plate on a turbocharged engine running boost closes, high pressure in the intake system has nowhere to go. It is forced to travel back to the turbocharger in the form of a pressure wave. This results in the wheel rapidly decreasing speed and stalling 

For customer adjustment consideration:

The spring should be set as soft as possible without leaking boost at peak pressure.
If the spring is set too soft, the valve will not close fully, resulting in a boost leak and idle problems.
If the spring is set too hard, the valve will not fully open, close too early, and cause compressor surge. Trial and error with an accurate boost gauge is the perfect way to find the right setting for your vehicle.
