All New Boost Tee

Ensure you have an over-boost cut-out. This is a safety feature built into basically all factory, aftermarket & programmable ECU’s. Make sure it is set at a sensible & reasonable limit. Increasing the boost will put more load on your engine, and there are other tune-related factors you must always consider. IF in any doubt, speak with a professional tuner/calibrator.

Suppose your engine is turbocharged and uses a boost-based actuation, then yes. The All-New Boost Tee by Turbosmart will work on any Boost-Based Internal Wastegate Actuators and External Wastegates. It will not be suitable for VGT (Variable Geometry) Turbochargers, also known as VVT (Variable Vein) and VNT (Variable Nozzle) or Vacuum-Based Actuators.

The maximum boost you will be able to make will come down to other variables with your setup. Turbocharger efficiency must be respected, and as such, as you start to work a turbocharger harder and towards the limits of its efficiency, a boost can be harder to achieve. With that said, on an otherwise efficient setup, you can expect to be able to achieve 1-2 times the base mechanical spring pressure as fitted to your actuator or wastegate.

Gate-Feature is a technology built into all Turbosmart Boost Controllers that promotes boost response and manipulates the reference signal for maximum gains. There is no other way to achieve such aggressive boost curves than the Turbosmart Gate Feature.

Yes! If maximum boost response is not what you’re after, you can disable this feature. Refer to the technical drawings & instructions as you will need to remove the ball and spring on the inlet side of the All-New Boost Tee.

Yes! This Arrow indicates the direction of flow of the reference signal (compressed air from the charge pipe or turbocharger) to the actuator. The Arrow direct must be respected & fitting the All-New Boost Tee backwards will result in boost control problems and instability.

No! The All-New Boost Tee design by Turbosmart increase’s the boost pressure above the base spring pressure. If you want to decrease boost pressure, you may need to change the spring within your actuator or external wastegate.

No! One-click either up or down on the All-New Boost Tee is not one psi. The actual change per click will be specific to your vehicle and your setup. The efficiency of every setup is different, and as such, the changes are not identical from vehicle to vehicle. We recommend making small changes at first to understand your setup first and foremost.
