The Turbosmart Boost Tee manual boost controller features Turbosmart's unique gated manual boost controller design, minimizing boost creep and spooling your turbo up to 800rpms sooner. Turbosmart gated boost controllers are tested to handle over 200% higher spring pressure than internal wastegates and 100% higher pressures for external gates. Built from high-grade brass and billet aluminum, Turbosmart Boost Tee boost controllers also feature the Turbosmart detent adjustment system for a smoother boost transition through the entire rpm range. Boost Tee manual boost controllers are simple to set up and mount under the hood in-line with the wastegate actuator. Kit includes all hardware, brackets and vacuum lines for a complete install in any turbocharged vehicle.
