GFB ATOMIC Manual Boost Controller

Go Fast Bits is known for making well-built turbocharger components, and their ATOMIC manual boost controller is a popular choice for tuners looking for a reliable way to manage boost pressure. This unit is designed for use with any turbocharged gasoline or diesel engine that uses a traditional pneumatic wastegate, whether it's internal or external. It's a single-stage controller that you can adjust right under the hood, offering a straightforward way to get more out of your turbo system.

Unlike some other manual boost controllers that use a ball-and-spring setup, the GFB ATOMIC employs a precision needle valve and orifice system. This design helps bleed off pressure from the wastegate line to increase boost, but it does so in a way that aims for a more stable and repeatable boost curve, avoiding the common issues of boost spiking and inconsistency that can plague other designs. Because it has no moving parts in its core pressure-regulating mechanism, it's also built for 100% reliability and requires zero maintenance, making it a set-and-forget kind of part once you have it dialed in.

Installation is straightforward, typically taking just minutes. This controller fits a wide range of turbocharged vehicles, including popular models like the Mitsubishi Eclipse, Subaru Impreza, and Toyota Supra. It's a solid option if you're looking for an effective and dependable way to control your turbocharger's boost pressure.
