Infinite is absolutely right. In order to avoild the drawbacks of the atmospheric bovs, you can typically, depending on the bov, route a tube that directs the released air back into the intake stream. It's not perfect but it usually works. That's the physical/hardware cure. There are also ways to compensate and get around this with his AEM.

In this case, I believe Web is running the standard pre-compressor pull through MAF setup; not a blow through.
