GrimmSpeed Black Manual Boost Controller 2002-2026 WRX / 2004-2021 STI
THE NEXT LEVEL OF BOOST CONTROL
Welcome to the most refined manual boost controller available on the market today. During development, we worked hand in hand with tuners across the country to develop this device and ensure that it solves legitimate problems that they have with other existing boost controllers. 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 and rock-solid boost control.
WHY?
The first boost controller of its kind, The GrimmSpeed Manual Boost Controller uses Exact Control Technology, with 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 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, instead, pinpoint your boost setting using the adjustment scale running the length of the controller
