The Go Fast Bits Deceptor Pro II Blow Off Valve (T9502) is an electronically adjustable, dual-port BOV engineered specifically for the Nissan Skyline GTS-T. Designed for turbocharged enthusiasts who demand precision control over boost response and venting character, the Deceptor Pro II allows you to dial in the perfect balance between atmospheric and recirculating venting — all without removing the valve. Whether you're building a street sleeper or a dedicated track weapon, this is the last blow off valve you'll ever need to buy.

Key Features & Benefits

• Electronically Adjustable Venting Bias — Seamlessly shift between 100% atmospheric (loud, classic BOV sound), 100% recirculating (OEM-style, MAF-safe), or any blend in between via the included controller, without tools or valve removal.
• Dual-Port Design — Combines the best of both worlds: enjoy the iconic whoosh of an atmospheric vent while maintaining closed-loop fueling stability on MAF-based ECUs — no lean surges, no stalling.
• Precision Boost Retention — Proprietary piston design holds boost under partial throttle and gear changes, eliminating compressor surge and protecting your turbocharger's compressor wheel.
• Direct OEM Replacement Fitment — Bolt-on installation engineered specifically for the Nissan Skyline GTS-T; uses factory mounting points with no cutting or fabrication required.
• Billet Aluminum Construction — CNC-machined from high-grade aluminum alloy for exceptional durability, heat resistance, and a premium aesthetic under the hood.
• Adjustable Spring Preload — Fine-tune the opening threshold to match your exact boost level, preventing premature venting on high-boost builds.
• GFB's Exclusive "Sound Symposer" Technology — Delivers a crisp, consistent venting note at any bias setting — not a muffled compromise.
• No Boost Creep or Surge — Unlike many aftermarket BOVs, the Deceptor Pro II is engineered to hold firm under sustained boost, keeping your tune consistent run after run.
