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
The Dr. Performance Module plugs into the engine ICP (Injection Control Pressure) sensor.
Step 2
The sensor is located near the front of the driver’s side engine head.
Step 3
The sensor can be seen more easily if you remove the cover on the top of the engine.
Step 4
Disconnect the factory plug from the ICP sensor (1).
Step 5
Plug the module harness into the ICP sensor.
Step 6
Plug the factory plug into the module harness receptacle.
Step 7
Route the harness to the left fender well.
Step 8
Reattach the cover, if removed.
Step 9
Plug the module harness into the module.
Step 10
Plug the selector switch into the module harness.
Step 11
Route the selector switch into the truck cab and mount in your desired location.
Step 12
Secure the module with zip ties provided or with velcro.
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.
