Reliable Boost Control Without Added Noise

Modern turbocharged engines push their factory diverter valves hard, often exposing weaknesses in plastic construction and inconsistent sealing. The GFB DV+ T9352 is engineered to resolve these shortcomings while retaining full factory ECU control and quiet recirculating operation.

What Makes the DV+ Different?

Unlike spacer-style solutions that only alter sound, the DV+ replaces the internal valve mechanism with precision-machined metal components while reusing the OEM solenoid. This approach keeps response times fast while dramatically improving boost sealing and durability.

Key Benefits

• Improved boost holding under load
• Sharper throttle response during partial throttle changes
• Faster boost recovery between gear shifts
• Recirculating design – no added noise
• Lifetime durability using metal and silicone components

Proven TMS Technology

GFB’s patented TMS (Turbo Management System) allows the valve piston to operate progressively instead of simply opening or closing. This improves drivability, reduces lag, and delivers smoother power delivery when modulating the throttle.

Direct Fit, OEM-Friendly Design

The DV+ T9352 installs directly in place of the factory diverter valve with no permanent modifications required. All factory electronics remain untouched, ensuring OEM-style behaviour with improved performance and reliability.
