Step by Step Instructions

Be sure your truck has been off for at least 10 minutes before installing the module to allow computer to "sleep" and for your engine compartment to cool down. This way it will not detect an interruption when you unplug your sensor.

Step 1:

Locate the fuel pressure sensor. It is located on the top of the fuel rail.

Step 2:

Disconnect plug from the fuel sensor. Plug male connector of module's fuel sensor plug into the truck's female connector. Next, plug female end of the modules sensor. Make sure the white arrow points to where the clip connects.

Push each connection firmly to ensure complete connection

Step 4:

Mount module away from the hot and/or moving parts. Zip ties are provided.

 

How The Selector Switch Works

The dial going clockwise:

Stock - Low - Medium - High

Low: Towing heavy and low traction situations.

Medium: Moderate towing and ideal for everyday driving situations.

High: Maximum performance - ideal for empty highway cruising.

The switch must remain plugged in to stay in the desired setting. You can run the switch into the cab or leave it tied up under the hood. Leave in one setting as much as possible.

Everyone has different driving preferences, it’s suggested that you try each setting for at least a week to see what you prefer.


If You Get a Check Engine Light or Hard Start Upon Installation:

Please check the connection between the truck’s wire harness and the module’s female plug and ensure it was connected properly. Improper installation will cause a CEL/hard starting.

Proper Harness Connection
