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.
Remove plastic engine cover.
Move rubber insulation aside on the front passenger side of the engine to expose the front of the fuel rail.
Unplug fuel pressure sensor on the end of the fuel rail. Plug our connectors inline. Pay close attention to the orientation of where our harness plugs into your factory harness. If it is plugged in upside down, it will not clip.
Zip tie or velcro your Stealth Module in a safe location away from direct heat.
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.
