No noise. No nonsense. Just results. The DV+ T9354 is the ultimate upgrade for those who want sharper throttle response and faster boost recovery, without the blow-off sound. It’s a direct factory replacement for pneumatic diaphragm-type BPVs used on Ford, Volvo, Porsche, and Borg Warner turbo systems.

Why Choose the T9354?

The DV+ T9354 improves on the weaknesses of the factory diverter valve by using GFB’s proven TMS (Turbo Management System) technology. By retaining factory ECU control and recirculating the air, the DV+ enhances performance while maintaining reliability.

Key Benefits

• Up to 30% faster boost recovery after gearshifts
• Sharper throttle response with progressive valve operation
• Fixes boost leaks common in stock valves
• Built to endure with high-quality metal and silicone construction

Boost Holding You Can Rely On

Unlike the factory BPV, which uses a soft diaphragm and operates in binary (open/shut) mode, the T9354 features a reinforced internal spring system and adjustable preload. This allows the valve to operate progressively, adjusting to varying throttle input and boost pressure for improved drivability and control.

The result? Better mid-throttle modulation and enhanced stability when balancing the car through corners.

Factory Weaknesses – Solved

The stock BPV is mounted directly on the turbo compressor, making it vulnerable to high intake temperatures. These harsh conditions can lead to diaphragm failure, potentially damaging the turbo if left unchecked. The DV+ T9354 is designed to withstand these temperatures, offering long-lasting reliability under demanding conditions.

How TMS Works

GFB’s TMS (Turbo Management System) technology allows the DV+ to respond more quickly and intelligently to boost changes. The result is quicker peak boost recovery (up to 30% faster than OEM valves) and superior performance without sacrificing response or ECU control.

Built to Last

Thanks to its metal and silicone construction, the DV+ T9354 is designed to last the life of your vehicle. Whether you're daily driving or pushing your car on the track, this is a mod that delivers dependable results – and you’ll never need to worry about replacing it.
