Go Fast Bits (GFB) Upgrades at JXL Performance

Engineered and manufactured in Australia, Go Fast Bits (GFB) has revolutionized aftermarket boost control. When tuning modern turbocharged engines, the factory boost management hardware is almost always the first critical point of failure. GFB specializes in precision machined diverter valves, atmospheric dump valves, and advanced boost controllers designed to permanently cure factory boost leaks. Whether you are running a standard map or a highly aggressive custom calibration, GFB hardware ensures that every single pound of boost generated by your turbocharger makes it directly into the engine block.

The Legendary DV+ Diverter Valve System

Modern factory diverter valves utilize a fragile plastic construction and a rubber diaphragm that frequently splits or perishes under increased boost pressure and extreme thermal stress. The GFB DV+ (Diverter Valve Plus) completely reengineers this flawed design.

Instead of replacing the entire factory unit, the DV+ smartly retains the incredibly fast electronic OEM solenoid but replaces the weak plastic valve mechanism with a heavy duty billet aluminum housing and a precision machined brass piston. This unique pilot actuated design ensures the valve can hold infinite boost pressure without leaking. By utilizing custom spring preloads, the DV+ drastically improves throttle response and provides incredibly fast boost recovery between gear changes. For enthusiasts wanting the classic turbo sneeze sound, GFB also offers atmospheric dump valves (VTA series) engineered with the exact same bulletproof internal mechanics.

Essential Upgrades for Fast Fords and EA888.3 Platforms

GFB diverter valves are a mandatory upgrade across the modern European tuning scene. For Ford enthusiasts, the factory valve on the 1.6 EcoBoost engine is notoriously weak. Installing a GFB DV+ on a Mk7 Fiesta ST is widely considered an absolutely essential first modification before flashing a Stage 1 or Stage 2 remap.

They are equally critical in the VAG world. The factory IHI IS20 and IS38 turbochargers found on the EA888.3 engine generate immense pressure that rapidly degrades the OEM diverter valve. Upgrading to a GFB DV+ is the ultimate bolt on reliability modification for the VW Golf GTI Mk7, the all wheel drive Mk7 and Mk7.5 Golf R, Audi S3 8V, and SEAT Leon Cupra 5F, ensuring your high horsepower build never suffers from a catastrophic high RPM boost leak.
