Manual Boost Controllers

Take control of the boost level in your turbo car with a GFB boost controller, one of the simplest and most cost effective power increases available.

The GFB Atomic/G-Force II boost controller is only for use on turbo systems that use a wastegate. It cannot be used to control boost pressure on VNT (Variable Nozzle Turbine)/VGT (Variable Geometry Turbine) turbos.
