Alex's Notes:
The OEM MazdaSpeed Bypass Valve/BPV  is well suited for up to 18-20psi of boost. Past this point it starts to leak air and torque drops off even if boost is maintained above 20psi. All big turbo cars should upgrade their BPVs. On some cars even the stock K04 turbo is hindered by a leaking OEM valve. The Synapse Valve is the fastest BPV on the market and you can run it as a BOV as well using our Guardian Angel. This valve won't leak even up to 60psi of boost and the fast response means excellent driveability as well as fast spool and excellent re-spool between shifts. Our BPV of choice for the MazdaSpeed.
If you want more information on why an upgraded BPV is important read our tech article here.
From Synapse:
Synchronic DV is the first, truly compact, zero-diaphragm, high-flow Diverter Valve with a blistering actuation time measured at 25 milliseconds. Mass air flow (MAF) and speed density (MAP) applications can apply the new design in push or pull orientation with the ability to fully re-circulate or vent-to-atmosphere the valve's discharge. Construction is based on near-net investment casting of aerospace-grade Aluminum for the body, followed by post-process CNC machining of all components including the forged billet 6061 actuator assembly. A complete selection of available mounting flanges are interchangeable between the SB and DV series and users can either upgrade from an existing BOV/DV by simply bolting on an adapter or weld on to a new project using the Aluminum or Stainless weld flanges. Boost/vacuum connections are made via 1/8th NPT threaded bosses that accept either Boost Connect or included nickel-plated-brass barb fittings. Each assembly is pressure tested to withstand 60 psi and positive lock clamshell retainers are included with each assembly for fitment.

This DV kit is also compatible with Mazda CX7, 1G/2G DSM, Nissan Skyline with RB20DET & RB25DET engines, 2008+ Subaru WRX (Non-STI) with OE TMIC.
