🔧 DV+ T9358 Diverter Valve
Upgraded Metal Diverter Valve with TMS Performance for Mercedes, Ford & Volvo Platforms
KEEP WHAT WORKS. FIX WHAT DOESN’T.
The DV+ T9358 is a direct-fit performance diverter valve developed by Go Fast Bits for modern turbocharged European engines. It retains the factory electronic control system while replacing the weak internal plastic valve components with precision-engineered metal parts for improved durability and response.
⚙️ KEY FEATURES
- Retains factory ECU-controlled solenoid (no rewiring required)
- Replaces internal plastic valve with billet aluminium + brass piston
- Direct-fit upgrade (no extra vacuum lines or adapters needed)
- Integrated TMS (Turbo Management System) technology
- Designed for high-boost, tuned applications
- Faster response than OEM diverter systems
🚀 PERFORMANCE BENEFITS
⚡ Sharper Throttle Response
Reduces delay in valve operation during gear changes and throttle lift.
🔁 Faster Boost Recovery
Helps the turbo return to peak boost more quickly after shifting.
🔒 Stronger Boost Holding Capability
Eliminates factory valve leakage under higher boost levels.
🧠 OEM Smoothness Maintained
Keeps factory drivability while improving performance characteristics.
🔬 HOW DV+ TMS WORKS
Instead of fully replacing the system, the DV+ improves it:
- ECU still controls the solenoid (fastest possible actuation)
- Internal valve is upgraded to high-strength metal components
- Pilot-actuated design improves precision under boost
- Only opens as much as required (not just fully open/closed like stock)
👉 Result: better control, faster response, zero complexity
🧩 ENGINEERING ADVANTAGE
Compared to full aftermarket BOV systems:
- No long vacuum hose setups
- No external springs or rebuild kits
- No slow pneumatic conversions
- No compromise in response speed
Instead, DV+ keeps the factory’s fast electronic control and upgrades the weak mechanical side.

💡 WHY THE T9358?
Because it fixes the weak point in the factory system without tearing it apart. You keep the fast ECU control, and upgrade the valve to something that actually holds boost and responds properly under load.
