Step by Step Instructions

Let your truck sit with the hood popped, doors shut and the key fob away from the vehicle for at least 20 minutes. It is important to keep the key fob away and the doors shut during the entire installation process. DO NOT bring the key fob near the vehicle or open any doors until AFTER the module is fully installed and connections are verified. This allows the computer to 'sleep' and for your engine compartment to cool down. Failure to do so will result in a check engine light on startup.

 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.

Turn Dial Clockwise

Stock - Low - Medium - High


Low - Towing at or near the vehicles maximum legal tow rating and low traction situations.
*consult your owners manual for vehicle tow rates

Medium - Moderate towing, around the middle of your vehicles tow rating, and ideal for everyday driving situations.

High - Maximum performance. Ideal for empty highway cruising.

The switch must remain plugged into the Stealth Module to remain in the desired setting. Do not switch power levels with the engine running.

You will see the best results when the selector switch is left in one setting for as long as possible.

Check Engine Light or Hard start on Install?

The most common reason for a check engine light on install is due to the truck not being asleep. If the Stealth Module has already been removed, please start the installation process over while giving special attention to the instructions above step 1. If the Stealth Module is still installed, verify connections and disconnect the negative terminals on your battery for a hard reset. Events that will wake the truck up: Not letting it sit for 15 minutes, opening/closing the vehicle door, having the key near the truck during install.

The most common reason for a hard start on install is due to improver connection. Please verify that all connections are straight and pushed in all the way. Be sure the harness is pushed in tight to the Stealth Module as well.

Remove the Stealth Module Before Service

Before going in for service, please remove the Stealth Module so that the truck is back to stock. This allows the technician to have a fresh base line when performing any work.
