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.
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. CNC machined from 6061 Aluminum, anodized and laser etched, our MBC is designed to outlast your car. The GrimmSpeed Manual Boost Controller redefines precision control and will deliver the results that you demand.
Will work with any OEM or Aftermarket turbo application.
Over all fantastic. From the ordering process, to how fast the shipping is and also the customer service. This is why I only shop on GenRacer for my coupe! Keep up the stellar work

I recently purchased the ARK test pipes for my 2010 Hyundai Genesis Coupe 3.8 and must say was the best thing I’ve done aside from from getting my aftermarket exhaust. Sounds louder and drives faster! No hassle, got the pipes within three days. Thank you GenRacer,

Most places just sell parts and when you call them it feels like you are bothering them. My last transaction with GENRACER left nothing to be desired, meaning it could have not been better. I purchased front and rear WHITELINE sway bars, front & rear DBA rotors, and EBC YELLOWSTUFF brake pads. I called just after I ordered the parts because I received an "out of stock" email notification. When I called back to chat with someone *** answered the phone. He couldn't have been more knowledgeable about exactly what I was looking for when it came to the right brake pad for my needs (street/track). Come to find out the pads I picked (DBA's) were not the best pads for my application so im very glad I talked to ***!! I just recently had everything installed, bedded the pads and I am so happy I used GenRacer for my 16 R-Spec Coupe!! Thanks again ***!!!

Order came fast and looks amazing on my car. I did have one problem where one tail light would blink sequentially and the other didn’t. I sent an email late in the day inquiring about it. I wasn’t expecting a response until at least the following day as it was so late. Within an hour they had gotten back to me informing me of a switch on the inside of the housing where you can choose sequential or regular. Sweet! Top notch customer service.
