The Boost Control Module instructs the vehicle's ECU to increase the amount of pressure in the manifold to a higher level before releasing it through the wastegate, keeping more boost available for when you need it (up to an estimate 49 horsepower and 82 lb./ft. of torque). The module reads the MAP (manifold air pressure), preventing over-boost and ensuring that power is added safely. Everything you need to set up your Boost Control Module, including the control module, wiring harness, and complete instructions are included. Featuring easy plug & play installation, it can typically be installed and ready to use in 30 minutes or less!
