$139.94USD (Excl. Sales Tax)
Control the boost from the driver’s seat. Ideal for the active enthusiast who wants boost adjustment on the run. Detent System makes adjusting a breeze. Gated System brings boost on faster.
The Turbosmart Gated Boost Control Valve range is one of the best dollar-for-horsepower upgrades you can make to your turbocharged petrol or diesel engine vehicle.
All Turbosmart Gated Boost Controllers feature our exclusive Gate feature, which minimizes wastegate creep and can improve turbo response by up to 800 rpm earlier in the rev range – this means you can increase the performance and response from your engine without even raising the maximum boost level.
Stable increases in boost over wastegate spring pressure of 200%+ for internal and 100% for external wastegates are standard practices using our manual boost controllers.
Manufactured from high-grade brass and billet aluminium and are renowned for their easy installation, robust design, and stability. Our detent adjustment system allows for accurate and simple tuning of boost pressure.
The Turbosmart Gated Boost Control Valve range is ideal for mildly modified turbocharged engines and is perfect for increasing boost levels on factory turbo cars and engines.

Turbosmart Boost Tee
What’s the first rule of boost control?
Ensure you have an over-boost cut-out. This safety feature is built into all factory, aftermarket & programmable ECUs. 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 factories you must always consider. If in any doubt, speak with a professional tuner/calibrator.
Can I use this on any turbocharged engine?
If your engine is turbocharged and uses a boost-based actuator for control, then yes. This Boost Controller will work on boost-based internal wastegate actuators and external wastegates.
How much boost can I add?
This will come down to the rest of your setup & tune. If in any doubt, we recommend you contact a professional tuner or workshop for advice here.
What is Gate Feature?
Gate Feature is a unique Turbosmart feature that ensures our boost controllers can give you the best possible response. Turbosmart’s Boost Controllers can provide the most aggressive boost curve by manipulating the pressure signal into your actuator.
Can the ‘Gate Feature’ be disabled?
Yes. Looking at the technical drawings available online, you will see the ‘Gate Ball’ and ‘Gate Spring’ behind the inlet nipple. Removing the nipple and re-assembling the Boost-Tee without the Gate Ball & Spring will provide you with the same type of control you expect from Turbosmart without the gate feature enabled.
Is the arrow important?
Yes. If you’re having issues with boost control, please take a minute and check your connection method and ensure the hoses are routed correctly – Take note of the arrow on the boost-Tee.
Can I turn my boost down?
Using a correctly installed Turbosmart Boost-Tee, you can adjust boost from around your base mechanical spring pressure (in your wastegate or actuator) up to usually around 2-3 times the base pressure. However, you cannot use these devices to turn the boost down lower than the base spring pressure.
Is one click one PSI?
No. One-click either way is relative to your engine and your turbo. The more efficient it is, the fewer clicks you need to achieve more boost. However, as the boost rises, efficiency decreases. This means that at higher boost levels; you’ll need to work harder (more clicks) for more boost.
