Installation steps

1. Use compressed air to blow out dirt and dust around the fuel rail and injector seats.
2. Using a T30 socket, remove the (2) Torx screws securing the fuel rail to the plenum.
3. Lift the fuel rail upward and back (without removing the injectors) – this will make it easier to disconnect injector plugs. Squeeze the retainer clips to release plugs from injectors and remove.
4. Move fuel rail to the passenger side of the engine so it is easier to work on. Use a small flat blade screwdriver to remove the injector clips securing the injectors to the fuel rail – make note of their orientation as they will be installed the same on the new injectors.
5. Apply di electric (silicone) grease on the top and bottom O-rings of the new injectors.
6. Install the injectors into the fuel rail in the same orientation as they were removed.
7. Reinstall clips making sure they are installed onto the injectors in the groove the same as they were on the OEM injectors.
8. Reconnect injector plugs.
9. Reinstall fuel rail hold down bolts – DO NOT OVERTIGHTEN.
10. Push start button, but do not start the engine – check for fuel leaks – if there is any leaking of fuel from the injectors or fuel rail, this must be addressed prior to running the engine.

Wastegate adjustment

Only for tunes that require it.

1. Remove panel between the seats that allows access to the turbocharger.
2. Using a small flat blade screwdriver, remove the clip that holds the wastegate actuator rod onto the wastegate arm.
3. Using a 10mm wrench, loosen the jamb nut on the wastegate rod.
4. Remove the wastegate rod end from the wastegate arm. Screw the rod end clockwise to shorten the arm to raise the crack pressure. Conversely, lengthen the rod to lower the crack pressure. Check crack pressure with Mityvac. Please see our YouTube video for the correct way to do this https://youtu.be/qOg2MnBfl08.
5. Check pressure 3 times to make sure it is correct.
6. Put the wastegate rod end back onto the wastegate arm.
7. Reinstall the clip and tighten the jamb nut.

Multi Map installation

For customers that have purchased the V-Map Multi Map option. Multi Map enables customers to use the “Sport Mode” and “ECO Mode” switch to select different tunes. Included is a new switch cover labeled “Race Gas” and “Pump Gas”. Customers can switch between tunes using this feature.

1. Remove the factory sport/eco mode switch.
2. Install the Supplied EVP 95 Oct/91 Oct switch.
3. For a Stage 4RWI Tune with the Multi Map Option – 95 Octane Fuel is required.
4. How to make 95 Octane:
   • Or mix 1.5 gallons of 110 octane race fuel to 3.5 gallons of 91 Octane.
   • Or mix 2.5 gallons of 100LL or 100 octane race fuel to 2.5 gallons of 91 Octane.

2018 fuel pump installation

1. Remove plastics covering fuel tank. See picture below for location.
2. Locate the arrow on the top of the fuel pump. The arrow will face the passenger side of the vehicle.
3. Unplug electrical connector going into the top of the pump.
4. Unhook fuel hose by removing the red clip from the connection. Then push down on the fitting while pushing in on the back side of the fitting – then lift the fitting off the pump assembly.
5. Rotate pump assembly cap counterclockwise and remove. Remove assembly.
6. Install the 2018 fuel pump assembly in the reverse order. Make sure to reinstall the rubber gasket at the top of the fuel tank or the tank will leak.

The X3 engine tuned makes best power around 7900-8100 RPMS. Strongly consider a clutch kit from us or another reputable company to get the best performance and belt life out of your vehicle.
