Turbosmart Boost Tee Manual Boost Controller - Black

This Turbosmart Boost Tee uses a solid brass detent ball and spring system to hold your selected boost setting. It's a straightforward way to increase boost pressure beyond what the wastegate spring alone allows, giving you more power from your turbocharged engine. The black anodized aluminum body is well-built and designed to handle the pressures involved.

Installation is typically done inline with the boost source line going to your wastegate actuator. By bleeding off some of that signal, you can trick the wastegate into staying closed longer, thus raising boost. The detent system means you can feel distinct clicks as you adjust the setting, making it easy to dial in your desired pressure. It's a popular choice for tuners looking for a simple, effective manual boost control solution.

Keep in mind this controller is not CARB approved and cannot be shipped to California. Always ensure your engine management system is properly tuned to handle the increased boost pressure safely.
