Go Fast Bits Atomic Boost Controller Single Stage. Universal Fitment

The Go Fast Bits (GFB) Atomic Manual Boost Controller is one of the most proven and reliable boost controllers on the market. Known for its repeatable, steady boost curve, quick rise rate, and unbeatable value, the Atomic is the ultimate “bang-for-buck” turbo upgrade.

In testing on a Subaru WRX (MY02), the Atomic delivered up to 18kW (23.4hp) more at the wheels compared to the factory boost control — without increasing peak boost. By allowing boost to rise earlier, spool-up improved by over 1700 RPM, resulting in faster acceleration and a much more responsive driving experience.

Unlike factory controllers, the Atomic is designed to get the most out of your turbo setup, transforming even a stock WRX into a car that finally feels like it has a turbo under the hood. And because it’s a manual boost controller, you get set-and-forget reliability with zero electronic failure points.

Key Features:

• Proven to deliver faster spool and earlier boost onset

• Stable, repeatable boost curve with precision control

• Pocket-friendly price with real-world dyno-proven gains

• Precision needle valve bleed system – more stable than ball-and-spring types

• Set-and-forget design – once adjusted, just drive

• Simple 2-hose installation – setup in minutes

• Rugged, mechanical build for 100% reliability, zero maintenance

• Suitable for conventional pneumatic wastegates

• Made in Australia, ISO 9001 certified

Whether you’re chasing quicker spool-up, smoother power delivery, or simply more fun from your turbocharged engine, the GFB Atomic Boost Controller is the perfect upgrade.
