Go Fast Bits BOVs, DV+ Kits & Boost Control for WRX, EVO, EcoBoost

What Go Fast Bits Covers

Blow-Off and Diverter Valves

GFB makes recirculating, atmospheric, and adjustable hybrid valve solutions. A correctly selected valve helps manage pressure when the throttle closes while preserving the configuration appropriate for the engine management system.

DV+ Direct-Fit Upgrades

DV+ kits are designed to improve the sealing and response of many factory electronic diverter valve applications. Confirm the original valve style and turbo configuration before ordering.

Boost Control and Wastegate Hardware

G-Force and Deceptor Controllers

Electronic boost controllers give a tuner control over boost targets when paired with a compatible solenoid, plumbing layout, and calibration. A boost controller is not a substitute for a proper tune.

Wastegate Actuators

An upgraded actuator can provide a more stable mechanical boost-control foundation on selected turbo applications. Verify actuator travel, bracket geometry, preload instructions, and tuning needs.

Selecting a Valve Configuration

Recirculation and Atmosphere

Recirculating valves return air to the intake tract and are commonly preferred on mass-airflow-metered applications. Hybrid valves allow an adjustable mix of recirculated and atmospheric discharge where the vehicle and tuning allow it.

Spring and Fitment Details

Choose a direct-fit kit whenever one is available. For universal valves, confirm flange type, hose diameter, vacuum reference routing, and the boost range of the application.

How to Choose the Correct Go Fast Bits Parts

• Confirm the exact vehicle, engine, turbocharger, and factory valve arrangement
• Decide whether recirculating, atmospheric, or adjustable hybrid operation suits the engine management system
• Check the valve inlet, outlet, and flange dimensions before ordering universal parts
• Verify the target boost range and spring recommendations for the selected valve
• Confirm whether an actuator or boost control change requires a tune
• Use boost-safe vacuum hose and secure clamps for every reference line
• Set wastegate actuator preload according to the manufacturer instructions

Common Questions

What does Go Fast Bits make?

Go Fast Bits makes blow-off valves, diverter valve upgrades, boost controllers, wastegate actuators, and related turbocharger hardware.

What is a GFB DV+ kit?

A DV+ kit is a direct-fit diverter valve upgrade for selected turbocharged vehicles. It is designed to improve the factory valve mechanism while retaining an application-specific fit.

Will a GFB blow-off valve fit a WRX STI?

GFB offers selected direct-fit valves for WRX and STI applications. Use the product fitment filter to confirm the exact chassis, engine, and model year.

Do I need a tune for a GFB boost controller?

Yes. Any change that alters boost targets or wastegate control should be paired with a proper calibration for the vehicle and fuel.

Should I choose a recirculating or atmospheric valve?

Recirculating is commonly the safer choice for mass-airflow-metered vehicles. Choose the configuration recommended for the vehicle and its tuning strategy.

What is the Respons TMS valve?

The Respons TMS is an adjustable GFB valve family that can provide a configurable balance between recirculated and atmospheric discharge on compatible applications.

Can a blow-off valve fix a boost leak?

A properly sealing valve can address a failed factory valve, but all charge pipes, couplers, clamps, and vacuum lines should also be pressure-tested.

What is a wastegate actuator?

A wastegate actuator uses boost pressure and spring force to move the wastegate mechanism. It helps establish the mechanical basis for turbo boost control.

Can I install a GFB valve myself?

Experienced DIY owners may install direct-fit kits. Follow the instructions closely and check for vacuum and boost leaks before driving hard.

How do I verify Go Fast Bits fitment?

Filter products by year, make, model, trim, engine, and drivetrain, then read the application notes for the specific valve or controller.
