Step 1: Locate the Stock Boost Source
The first step in the installation process is to locate the stock boost source. This is typically found on the intake manifold or near the throttle body. You may need to remove some components to access it easily.
Step 2: Disconnect the Battery
Before proceeding with any electrical work, disconnect the negative terminal of the battery. This will prevent any accidental shorts or electrical issues while installing the boost controller.
Step 3: Remove the Stock Boost Line
Using your socket set, carefully remove the stock boost line from the boost source. Be cautious not to damage any surrounding components during this process.
Step 4: Install the Boost Controller
Now, it’s time to install the boost controller. Follow these sub-steps:
- Attach the boost controller to the stock boost source.
- Connect the boost line from the controller to the wastegate actuator.

Step 5: Reconnect the Battery
After installing the boost controller, reconnect the negative terminal of the battery. Make sure it is tight and secure to avoid any electrical issues.
Step 6: Start the Engine
Start your engine and allow it to idle for a few minutes. This will help you check for any leaks or issues with the installation. Monitor the boost gauge to ensure it is functioning correctly.
Step 7: Adjust the Boost Controller
Once the engine is running smoothly, it’s time to adjust the boost controller settings. Follow these guidelines:
- Refer to the boost controller’s manual for specific adjustment instructions.
