By purchasing this kit, you agree to and understand the following:

  • This is a high-performance upgrade!!!! Although we have gone through great lengths to build safety into the upgraded tuning, the fact is installing any performance-enhancing product from any company requires care in both operation and/or installation. Poor fuel, improper setup, or any number of things that are done incorrectly can damage your engine/vehicle.
  • You have likely voided the sound and exhaust emission standards of your state, county or country if applicable.
  • This upgrade is intended for OFF ROAD or for racing use only.
  • The fuel requirements must be adhered to!!!! Poor fuel can destroy an engine in seconds!!!
  • Due to the variability of fuel quality and other factors, Evolution Powersports (EVP) bears no responsibility for damage caused to your vehicle by the installation of EVP products. The warranty on our parts is 90 days from the date of purchase. Evolution Powersports, at its discretion will determine whether a part meets the warranty requirements. In no case is there any warranty from EVP for your vehicle. We assume no liability for damage to vehicle or personal injury from installing or using any of our products.
  • The installation of some aspects of this kit are technical and mechanical in nature with opportunities to make mistakes – mistakes that can be very costly!!! If you are not qualified to install this kit, don’t do it!!
  • This kit will make your vehicle faster, climb higher and accelerate more quickly and take a longer distance to brake than a stock-tuned vehicle. If you are not capable of controlling the vehicle with the added performance, do not install the kit.
  • Do not ever allow a child or an unqualified driver to operate this vehicle!
  • The Multi Map option must be used carefully – running in “95 octane mode” with poor fuel can damage your engine quickly. Absolutely no warranty is expressed or implied due to the possibility of running the engine in the wrong mode.
  • By installing our products on your vehicle, you agree to the above terms and conditions.

Step 3: Install EVP charge tubes
Step 4: Connect intercooler fan to OEM harness plug (there is a provision for this on the 120 hp version.)

Stage S-R:
Step 1:

Step 4: Recommended: Re-gap OEM Spark Plugs to 20 Thousandths (0.020)

Installation Steps:

NOTE: Engine must be cold to do this install.
Step 1: Use compressed air to blow out dirt and dust around the fuel rail and injector seats.
Step 2: Using a T30 socket, remove the (2) Torx screws securing the fuel rail to the plenum.
Step 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.
Step 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.
Step 5: Apply di electric (silicone) grease on the top and bottom O-rings of the new injectors.
Step 6: Install the injectors into the fuel rail in the same orientation as they were removed.
Step 7: Reinstall clips making sure they are installed onto the injectors in the groove the same as they were on the OEM injectors.
Step 8: Reconnect injector plugs.
Step 9: Reinstall fuel rail hold down bolts – DO NOT OVERTIGHTEN.
Step 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)
NOTE: See picture on next page for clarification of this procedure.
Step 1: Remove panel between the seats that allows access to the turbocharger
Step 2: Using a small flat blade screwdriver, remove the clip that holds the wastegate actuator rod onto the wastegate arm
Step 3: Using a 10mm wrench, loosen the jamb nut on the wastegate rod
Step 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
Step 5: Check pressure 3 times to make sure it is correct
Step 6: Put the wastegate rod end back onto the wastegate arm.
Step 7: Reinstall the clip and tighten the jamb nut.

Multi Map Installation:

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

NOTE: You must be careful using this function – Running in “RACE GAS MODE” when “PUMP GAS” is in the tank can damage your engine.
