Boost Tee Boost Controller Blue (SUPERSEDED)
$95.01USD (Excl. Sales Tax)
Smaller and lighter than other Manual Boost Controllers on the market. Set your boost and forget it. Boost adjustable from under the hood with an accurate, proven Detent System. Easy to install and adjust.
The Turbosmart Gated Boost Control Valve range is one of the best dollars for horsepower upgrades that 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 that 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 wastegate and 100% for external wastegates are common practise using our manual boost controllers.
Manufactured from high-grade brass and billet aluminium and are renowned for their easy installation, robust design, stability, and our detent adjustment system allows for accurate and simple tuning of boost pressure.

What’s the first rule of boost control?
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 is another tune related factory 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 wastegate flap style control, then yes. This Boost Controller will work on boost-based internal
wastegate actuators and external wastegates. It will not work for VGT (Variable Geometry) Turbochargers, also known as VVT (Variable Vein) and VNT (Variable Nozzle) Turbochargers.
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
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 will
be able to 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
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 boost rises, efficiency decreases. This means you’ll need to work harder (more clicks) for more boosts at higher boost levels.
