It is not a WG. We control the BPV with a MAC solenoid via hijacking the EVAP purge valve signal going to the ECU which can then be controlled through Ecutek (map switching using your cruise control buttons) or by a standalone boost controller like the Innovate SCG-1.
If your going boosted the SCG-1 is really your best option as it displays Boost, AFR and allows you to dial in boost on the fly, in an all-in-one gauge.
