Features:
The GrimmSpeed Boost Control Solenoid is the most complete and easy to use 3-Port Electronic BCS. Unlike your OEM 2-port solenoid, the GrimmSpeed BCS will allow for extremely high resolution boost control at elevated boost pressures, providing your tuner with the hardware needed to safely tune your car with rock solid boost levels. Using our solenoid, you are able to spool your turbo quicker and maintain tight control of boost levels throughout your power curve, allowing you to run the max safe boost at any point in the rev range. In addition, our solenoid features a balanced valve to withstand up to 120psi without a slowing response by even a single millisecond.
