GFB Manual Boost Controllers may lack features of an EBC, but they get the job done!

Boasting a repeatable and stable boost curve, quick rise rate, and unbeatable value, GFB's Atomic has earned a reputation as being one of the most reliable and effective manual boost controllers on the market. It is important to note that the Atomic does NOT use a "ball-and-spring" system like others on the market, for very good reason; The ball-and-spring system is an attempt to increase the boost rise rate by preventing pressure from reaching the wastegate during spool up; However, in practice this method usually creates boost spiking and a less stable and repeatable boost curve; Instead, the Atomic uses a precision orifice and needle valve system to accurately bleed pressure from the wastegate line to increase boost; With no moving parts, this system is ultimately more reliable and stable.For use with any type of petrol/gasoline or diesel turbocharger system using a traditional pneumatic wastegate (internal or external).
