Do I need a BOV for a 7 psi turbo setup?

For a 7 psi turbo setup, a blow-off valve (BOV) is generally recommended to prevent compressor surge, which can occur when the throttle is closed suddenly. A BOV helps to release excess boost pressure, protecting your turbo and enhancing throttle response. While some setups may operate without one, using a BOV can improve reliability and performance. Ultimately, whether you need one depends on your specific configuration and goals.
