⚡ THE SIMPLE & ESSENTIAL MOD FOR SHARPER BOOST RESPONSE

UTILISING PROVEN GFB TMS TECHNOLOGY TO DELIVER FASTER BOOST RECOVERY, IMPROVED THROTTLE RESPONSE, AND RELIABLE BOOST HOLDING

If you don’t need a full replacement diverter system, the DV+ T9351 is the ideal OEM+ upgrade — retaining factory ECU control while upgrading the weak internal valve components.

Using GFB’s Turbo Management System (TMS), the DV+ helps the engine return to peak boost up to 30% faster than the factory diverter valve during gear changes.

🔬 TMS TECHNOLOGY EXPLAINED

GFB’s Turbo Management System works by:

• Retaining ECU-controlled solenoid operation
• Replacing weak OEM valve internals with precision machined components
• Allowing faster and more stable valve actuation under boost
• Improving response during rapid throttle changes

👉 Result: more consistent boost control, faster spool recovery, and improved drivability.

⚙️ ENGINEERING OVERVIEW

Factory VAG diverter valves commonly fail due to:

• Plastic piston wear or leakage under boost
• Diaphragm rupture on tuned engines
• Slow or inconsistent sealing under load

The DV+ T9351 solves this by upgrading only the valve mechanism while retaining the fast-reacting OEM solenoid system.

This approach delivers:

• Faster response than full aftermarket pneumatic replacements
• Better durability than factory components
• Simplified installation with OEM fitment
