All New Boost Tee Manual Boost Controller (Blue)

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 as well as 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 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 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 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 boost rises, efficiency decreases. This means you’ll need to work harder (more clicks) for more boosts at higher boost levels.
