Step by Step Instructions

Be sure your truck has been off for at least 10 minutes before installing the module to allow the 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:

Remove engine cover for easier access to fuel and MAP sensors.

Step 2:

Locate the fuel sensor just below the air intake at the end of the fuel rail. It is black with yellow grommet, For easier access to fuel sensor, disconnect the intake tube.

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.
