The GFB Respons TMS (ref. T9001) is engineered as a direct bolt-on blow-off valve for the Subaru WRX 2008-2014 and Forester XT 2009-2013. GFB's patented TMS (Turbo Management System) venting bias adjustment delivers precise control from 100% recirculation (silent) to 100% atmosphere (full blow-off sound). Boost recovery is up to 30% faster than the factory diverter valve during gear shifts, even on sensitive MAF-based systems. No modifications required — everything needed for a bolt-on install is included.
