Factory bypass valves they are often undersized and are quickly beyond their capable operating range as airflow levels are increased. Upgrading your BOV will increase engine performance from quicker turbo spool up, as the compressor speed is not reduced by the backwards airflow.

The life and quality of the turbo is also increased, as it will not suffer from the harsh and negative impact that is also produced by compressor surge.. Certain applications will need adaptors available from any exhuast installers otherwise easily DIY
