Superior Range with Ultra-Fine Resolution!
Welcome to the next evolution of boost control, The GrimmSpeed Manual Boost Controller. Introducing the most refined Manual Boost Controller available on the market. We spent over a year working hand in hand with tuners across the country to devolop our MBC. Our Manual Boost Controller allows you to raise the OEM boost levels in a quick and efficient manner.

This is the first of its kind with Exact Control technology utilizing over 250 adjustment points that lock in place using a heavy duty stainless dual ball detent system. An extra long travel spring gives you superior range unmatched by any other manual boost controller while maintaining a high resolution, not some vague guess at where to set your boost. Don't trust the life of your engine to trial and error, rather pinpoint your setting using our rising scale running the length of the controller, lock and load. CNC’d from weapon’s grade 6061 Aluminum and laser etched our MBC will outlast your vehicle! The GrimmSpeed Manual Boost Controller redefines precise control and will promise you the results you demand.

Pierburg 3 Port Boost Solenoid 15+ WRX
Regular price $198.95 Save $-198.95
Unlike the factory solenoid,this 3-Port Solenoid allows you to raise the factory boost levels with more response and adding more control.
With this solenoid no boost pressure is allowed through to the actuator so no premature boost can occur. The 3-Port Solenoid allows lower wastegate duty cycle to produce higher boost pressures with much greater control,thereby allowing tuners more “headroom” and “space” when modifying high horsepower turbo vehicles.
The kit includes the 3-Port Boost Control Solenoid and harness for plug and play install with Subaru 2015+ WRX and Brackets to make it for easy Plug and Play application.
