Grimmspeed Boost Control Solenoid 3-Port for the Subaru WRX STI

Subaru WRX STI Boost Control Solenoid by Grimmspeed
Upgrade your stock manual boost controller with Grimmspeed's Electronic Boost Control Solenoid and hold onto more boost. The Boost control solenoid by Grimmspeed is the perfect solution for individuals who are tuning their vehicles for more boost and horsepower. This controller won't reduce the life of your computer because it is designed to draw the same amount of power as the factory BCS but flows better and reacts faster to boost levels.

The benefits of fitting an electronic boost control solenoid onto your Subaru WRX is that you get better control of your boost levels at all RPM ranges. For instance: say you set your Manual Boost Controller (MBC) to 18 psi because from 3000-6000 RPM that is what you want. But say at 8,000 RPM you get detonation unless you are at 16PSI. You must therefore run 16psi during all RPM ranges to solve the detonation that occurs at 7,000 RPM. With the Grimmspeed boost controller you can set your boost to 18 psi like originally intended and then lower it to 16psi during the 7,000 RPM range. This gives you full customization of your boost levels that the stock manual boost controller does not allow for.
