Overview

The Go Fast Bits T9007 Respons TMS is a direct-fit blow-off valve designed to improve performance and sound. It features a patented, adjustable venting bias system that allows precise control over how much air is vented to atmosphere or recirculated. This system enables users to adjust the volume of the blow-off sound from silent to maximum noise, or anywhere in between.
Show original supplier description
Unlike traditional dual-port BOVs, the Respons TMS incorporates GFB's patented venting bias adjustment system, enabling precise control over the air vented from its two outlets. This feature allows users to customize the blow-off sound, ranging from completely recirculated for factory-quiet operation to fully atmospheric for an audible release, or any setting in between. The valve's design ensures unlimited boost holding capability, preventing boost leaks even at high pressures due to its balanced piston construction. This system is also compatible with sensitive Mass Airflow (MAF) sensor-equipped vehicles, avoiding common issues like stalling or backfiring associated with other atmospheric vent valves. The unit is constructed from aluminum. The following vehicle applications are confirmed for the T9007 model: 2015-2021 Subaru WRX VA, 2013-2018 Subaru Forester XT SJ, and 2014-2021 Subaru Levorg VMG.
