Synapse Synchronic Bov
"By design, it is a pull-type valve only. This means that boost pressure keeps it closed, meaning no boost leaks upwards of 100+ psi of boost. It operates in a normally open condition. This means that it is designed to remain open under vacuum conditions. For maximum performance and reliability, it is recommended to install the Synchronic BOV in a re-circulated configuration with the discharge between the MAF sensor and turbocharger inlet. "
