🔧 Product Description

The GFB DV+ for 1.4 TSI Twincharged Engines is a high-performance OEM diverter valve upgrade designed specifically for Volkswagen Group twincharged turbo systems.

GFB’s DV+ system retains the factory ECU-controlled solenoid while replacing the weak internal plastic valve components with a precision-engineered metal assembly. This delivers significantly improved reliability, sharper throttle response, and stronger boost control under both stock and tuned conditions.

Built on GFB’s proven TMS (Turbo Management System) technology, the DV+ provides faster boost recovery, improved drivability, and consistent boost holding across a wide range of driving conditions.

🔬 TMS Technology Explained

GFB’s Turbo Management System (TMS) optimises valve operation by:

• Keeping the valve securely closed under boost
• Opening instantly on throttle lift
• Maintaining stable airflow during gear changes
• Reducing compressor surge and airflow instability

👉 Result: improved spool recovery, sharper response, and more consistent boost delivery.

⚙️ Engineering Overview

The factory 1.4 TSI twincharged diverter valve retains a strong ECU-controlled solenoid, but the internal plastic valve mechanism is a known weak point—especially under increased boost or tuning.

The DV+ solves this by replacing only the valve internals with:

• Billet aluminium housing
• Precision-machined brass piston
• Reinforced sealing surfaces for long-term durability

This preserves OEM electronic control while dramatically improving mechanical strength and response.
