The GrimmSpeed Manual Boost Controller is the most refined manual boost controller on the market. Having spent over a year working closely with the nations best tuners, GrimmSpeed was able to produce the next step in the evolution of manual boost controllers. This GrimmSpeed Manual Boost Controller or "MBC" for short, allows you to dial in boost precisely to meet your requirements and bypass sub-par OEM methods of controlling boost for quicker response, quicker spool up increased horsepower and increased torque!

Using Exact Control Technology and a special stainless dual ball detent system, the GrimmSpeed MBC offers two hundred and fifty adjustment points that lock in place. Coupled with a long travel spring and ultralight ceramic ball valve, these features provide the highest resolution and quickest reaction possible when making adjustments. The weapons grade 6061 aluminum case can easily outlast the life of most vehicles and it also features a laser etched adjustment scale for quick and easy adjustments that eliminate "guesswork" when tuning. The GrimmSpeed Manual Boost Controller is a great value and redefines precise control to deliver the results you expect.

Key Features:
  • Works with OEM or aftermarket turbos.
  • Heavy Duty SST Dual Ball Detent System (clicks with each turn for positive feedback).
  • Easy to read laser etched adjustment scale.
  • Long travel spring (no need to switch springs for more travel).
  • 0-60 PSI adjustment range with ultra fine adjustments.
  • CNC'd from weapons grade 6061 aluminum.
Tuning Note: As with any boost controller, if used to raise boost significantly (more than 2-3 PSI) we strongly recommend a full ECU re-tune for best performance and engine life.
