How is the manual boost controller important for me?

If you are a turbo vehicle owner, you must understand the benefits of a manual boost controller. You can increase the amount of positive pressure by increasing the boost. Turbo vehicle owners can replace factory or stock boost control with a manual boost controller to get a great boost. It is essential to use a pressure gauge or boost gauge for increasing the boost.

How can I Install My Manual Boost Controller?

First of all, you have to gain access to your turbo. The next step is to locate your pressure source and wastegate actuator. Now you have to remove the factory hoses and replace them with new silicone hoses. Your hoses should be long enough according to the mounting position of the controller. You don’t need to remove the vent line from the solenoid, only disconnect the boost line.

Now, you can mount the boost controller. For this purpose, you can use the mounting bracket, which often comes with the installation kit. It is recommended to mount the controller closer to the turbocharger without leaving space between them. Shorter hoses are the signs of a better response. Make sure you have attached both hoses.

Now it’s time to adjust the boost. Look for the direction mentioned on the controller and turn the knob in the same order.

How can I adjust the manual boost controller for better performance?

After installing the controller, you can adjust the dial by turning it down. This is how the internal chamber of the controller creates more pressure on the spring. Do the process slowly and look at the boost gauge carefully.

This is the most critical point to get control of everything without causing any damage to the engine. The boost controller is installed inline of wastegate vacuum piping of your turbo. It will automatically control the desired boost.
