The GFB D Boost V2 (MPN 3009) is a precision-engineered manual boost controller specifically designed for vehicles equipped with VNT (Variable Nozzle Turbine) or VGT (Variable Geometry Turbo) turbochargers. Unlike standard bleed valves designed for pressure-actuated wastegates, the D Boost V2 utilizes a precision needle valve bleed system to provide stable and repeatable boost curves for vacuum-actuated systems.
- Precision Control: Features a high-accuracy needle valve for fine-tuning boost levels with absolute stability.
- Set-and-Forget: Once adjusted, the controller maintains consistent settings with zero maintenance required.
- Reliable Construction: Manufactured in Australia in accordance with ISO 9001 standards to ensure 100% reliability in demanding engine bay environments.
- Simple Installation: Designed for a straightforward installation process that can be completed in minutes.
Whether you are looking to stabilize boost spikes or optimize your VNT turbo's response, the D Boost V2 offers a robust, mechanical solution for precise boost management.
The GFB G-Force III Electronic Boost Controller (MPN 3008) is a high-performance boost management solution designed for precision and reliability in forced induction systems. Capable of handling boost pressures up to 50 psi (3.45 bar), this unit provides tactile, real-time control over your turbocharger's output.
Equipped with a high-flow 4-port MAC solenoid, the G-Force III offers a superior control range for wastegate positioning compared to traditional 3-port designs, making it an essential upgrade for high-boost applications and external wastegate setups. The interface features a capacitive touchscreen for seamless navigation through six fully programmable boost presets, allowing you to tailor performance to specific driving conditions.
- 4-Port Solenoid: Delivers enhanced control and stability for external wastegates and high-pressure setups.
- Scramble Boost: Instantly increases boost for a user-defined duration via the touchscreen or an external remote trigger.
- Overboost Protection: Actively monitors pressure and triggers a safety shutdown if boost exceeds your defined limit.
- Peak Hold Function: Displays the maximum boost reached during a pull for easy data logging and tuning.
- Adjustable Display: Features multiple illumination colors to match your vehicle's factory interior lighting.
The 3008 kit includes the G-Force III controller unit, a 4-port solenoid, a dedicated wiring harness, and all necessary vacuum fittings for installation.
