Step by Step Instructions
Be sure your truck has been off, with the hood unlatched and key fob located away from the vehicle for at least 15 minutes before installing the module. Key fob needs to continue to stay away from the vehicle for the entire installation process. This allows the computer to 'sleep' and for your engine compartment to cool down. It also helps mitigate your ECM from detecting an interruption in a sensors electrical circuit.
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.
Step 3
Disconnect the plug from the fuel sensor. Plug the male end of the module's fuel sensor into the trucks female connector. Next, plug the female end of the module's sensor into the truck's sensor.
Step 4
Push each connector firmly to ensure complete connection.
Step 5
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.
Remove The Module Before Service Work
If you need to take your vehicle in for service work, REMOVE the module before work is performed.
