We are proud to present the GrimmSpeed Manual Boost Controller, the most refined manual boost controller available on the market today. For over a year, GrimmSpeed worked hand-in-hand with tuners across the country to develop this boost controller. The GrimmSpeed MBC allows you to raise OEM boost levels in a quick and efficient manner through superior boost range and ultra-fine resolution (.25 PSI/click). Adding the MBC to your car will result in quicker spool up, quicker response, increased horsepower, and increased torque.

The first boost controller of its kind, the GrimmSpeed Manual Boost Controller uses Exact Control Technology, utilizing over 250 adjustment points that lock into place via heavy-duty stainless dual-ball detent system. An extra-long travel spring gives you superior range unmatched by any other manual boost controller on the market while maintaining a high resolution, not just a vague guess at where to set your boost. Don't trust the life of your engine to trial and error, rather pinpoint your boost setting using the adjustment scale running the length of the controller. CNC’d from weapon-grade 6061 aluminum, anodized, and laser etched, the GrimmSpeed MBC is designed to outlast your car. The GrimmSpeed Manual Boost Controller redefines precision control and will deliver the results that you demand.
