Overview

The GFB T9010 Respons TMS is a direct-fit blow-off valve (BOV) designed to replace the factory diverter valve. It features an adjustable venting bias system, allowing you to control the ratio of air vented to the atmosphere versus recirculated air. This system allows for adjustment of the blow-off sound volume and can be configured to provide a blow-off sound without causing stalling or backfiring, even on sensitive MAF-based systems.
Show original supplier description
The GFB T9010 Respons TMS is a direct-fit blow-off valve (BOV) engineered as an upgrade over factory diverter valves. It incorporates GFB’s unique venting bias adjustment system, enabling precise control over the proportion of air vented to atmosphere versus recirculated air. This feature allows users to customize the sound of the blow-off, from completely silent recirculation to full atmospheric venting, or any ratio in between. Beyond sound customization, the Respons TMS offers performance benefits. The valve also contributes to improved throttle response and faster boost recovery during gearshifts, with GFB claiming up to a 30% faster return to peak boost compared to a factory diverter valve, thanks to its Turbo Management System (TMS) principle. The balanced piston design ensures unlimited boost-holding capability, preventing the valve from being forced open by high boost pressures.
