Stock BOV leakage?

Stock BOV has a good spring on it. Really, you might be hearing the second turbo pre-spooling - the charge relief vents the boost from the second turbo back into the airbox below 4500 RPM.
Unless you have actual boost problems, I doubt there's anything wrong. A leaky BOV would show up as reduced boost patterns.
