The Turbosmart In-Cabin 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 In-Cabin boost controllers also feature the Turbosmart detent adjustment system for a smoother boost transition through the entire rpm range. The In-Cabin system is very similar to the standard Turbosmart Boost Tee however it ca be mounted in cabin for added tuning convenience. Kit includes all hardware, brackets and vacuum line for a complete install in any turbocharged vehicle.
