Product Description

The Go Fast Bits T9533 Deceptor Pro II Blow-Off / Diverter Valve Kit is a performance-oriented turbocharger component designed to give drivers real-time control over how their turbocharged vehicle vents excess boost pressure. Unlike fixed valves, this motorized valve lets you adjust venting bias electronically from inside the cabin using a backlit proportional dial - from full recirculation for quiet operation to full atmospheric venting for aggressive sound and performance tuning.

Featuring Go Fast Bits' Turbo Management System (TMS) technology, the Deceptor Pro II improves throttle response and can help reduce turbo lag by more efficiently controlling boost transitions compared with many factory diverter valves. The high-torque geared electric motor and low-friction gear train provide smooth, precise venting adjustment without sacrificing durability. Its compact design and included wiring hardware simplify installation in compatible turbo systems with 33 mm hose-mount diverter or blow-off valve locations.

Fitment for the Go Fast Bits T9533 is confirmed across a range of classic and performance turbocharged vehicles that use standard 33 mm hose diverter mounts. This includes Mitsubishi models such as Eclipse, 3000GT / Dodge Stealth VR-4, Galant VR-4, and many generations of Lancer Evolution and Ralliart variants, as well as the 1997-1998 Subaru Impreza WRX. This adjustable valve kit is ideal for enthusiasts seeking enhanced turbo management, customizable sound levels, and improved throttle response without the limitations of a fixed-bias valve.
