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 develop our MBC. Our Manual Boost Controller allows you to raise the OEM boost levels in a quick and efficient manner. Adding the MBC will result in Quicker Spool Up, Quicker Response, Increased Horsepower, and Increased Torque.

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.
