On a Dodge turbo-equipped vehicle, the primary function of the wastegate is to regulate the amount of boost psi, or pounds per square inch the turbocharger generates. It does this by metering the exhaust flow that hits the turbine wheel until the desired level is reached. Tuners wishing to liberate extra horsepower from an engine often choose to increase turbo boost, as this is a relatively simple modification which can yield substantial power gains. The most common way to do this is through a manual boost controller upgrade. This allows unlimited adjustment of a Dodge turbo wastegate, without the need to replace any hardware inside the unit.
Things You'll Need
- Boost controller kit
Attach one end of the controller to the external wastegate actuator inlet with the included silicon vacuum hose.
Connect the other side of the controller by slipping on the vacuum line to the boost outlet source, found on the compressor side of your turbo.
Use the included clamps and zip ties to secure the controller unit in an easy to reach area, away from hot spots such as the exhaust manifold.
Rotate the knob on the boost controller to restrict boost flow to the wastegate and adjust the units default settings. Typically clockwise will increase boost and vice versa.
Tips & Warnings
- Install a higher flow fuel system when dramatically raising psi levels.
- Use a wideband O2 sensor for tuning.
- Keep a close eye on air/fuel ratios to prevent running excessively lean.
