    @KLR STINGER seems to know a lot about BOVs. He can probably provide some good information on the topic.

    The issue: If the spring is too tight and there is NOT enough pressure to open the vale it stays shut or partially shut, which causes turbo flutter (this will cause premature wear of the turbo)

    How to fix it: Simply if you hear your turbos fluttering simply loosen the spring to reduce spring pressure, running like this for a short period will not cause any damage (couple weeks at most). Mind you if you leave it like that for extended periods (think months and months maybe even years) it will cause premature turbo failure.

    What is turbo flutter and why is it bad?: When your turbos are spinning they have turbine wheels that spin in a certain direction, think of like an airplane propeller or a jet engine. When the throttle body is shut (you take your foot off the gas) the turbines continue to spin and generate pressure so what happens is the BOV's will open to relieve this pressure and allow the turbines to keep spinning.

    This is where the issue comes, if there is NO BOV or it doesn't open or adequately the pressure has no where to go except backwards so it starts spinning the turbine wheel the other way and dumps the pressure out of the intake/turbo inlet. The turbines are spinning around 70,000-120,000 RPM then ALL OF THE SUDDEN.....BAM it goes backwards, this causes extra stress on the turbo which will lead to turbine failure.

    The Good: An aftermarket BOV will be able to open/react quicker then factory valves, take more PSI and speed up boost recovery after shifts.

    Modifying cars: Just like any aftermarket parts designed for your engine you don't just pop it in and ignore it, you need to be mindful and monitor it for any issues so you can resolve them. Such as if you put an aftermarket intake on the car, you should be rechecking it every now and then to make sure its still snug and nothing is lose etc... Same goes with this, IT IS NOT FACTORY so you need to give a little more care to it. If you don't want to have any additional work or upkeep keep your car stock as that was how it was designed by the engineers.
