FastUTV Can-Am Maverick X3 Turbo Tuning — 2018–2020 120 HP

Build a staged upgrade for the non-intercooled 120 HP X3. These tuning packages are for vehicles fitted with the required intercooler, fan and charge tubes; higher stages also need the matching Turbo R fuel pump.

Every package includes your selected FastUTV calibration, RTD4 tuning interface, correct Can-Am adapter cable and required licensing.

Package choices

• $799: tuning, RTD4, cable and licensing with the stage’s required injectors already fitted.
• $1,499: the same package plus three new, matched 1000cc injectors for a big-injector stage.
• New wastegate: +$299 when selected for a big-injector stage. Reusing a suitable installed actuator adds no parts charge.
• Turbo R conversion pump: +$323 when selected for a pump-conversion stage.

Only combinations matching the selected stage are offered. “Installed” means that the correct supporting parts are already on your vehicle. Parts marked “add” or “supply” in the tuning options are included in the tuning price. Cooling parts and charge tubes selected beside Add to cart are separate products; the combined total is shown before adding them together.

Vehicle fitment

2018–2020 factory 120 HP Maverick X3 Turbo models, including MAX four-seat and applicable X mr/X rc Turbo trims. A complete model-year-matched intercooler conversion is required for every stage listed here.

Choose by model year and original factory horsepower. FastUTV matches the delivered file to your ECU, injector specification, fuel and installed hardware.

Stage and fuel guide

The crank HP and wheel HP below are EVP’s published reference figures for these configurations, checked October 6, 2026. They describe the guide’s test setups; your result depends on fuel, build and test conditions.

Octane ratings are US AKI. Select one fuel-specific calibration. E85 stages require fuel matched to the calibration’s ethanol content; gasoline and E85 files are separate. These are fixed-fuel stages.

Supporting hardware and setup

Every listed stage requires a complete, model-year-matched intercooler, fan, mounting/connection hardware and intercooled charge-tube conversion before the tune is used. Choose your vehicle year and cooling parts beside Add to cart to buy them from FastUTV with the tuning package, or confirm that the required conversion is already installed. Cooling products are additional to the tuning price and appear as separate cart lines. Connect the fan at the correct provision. Stage 1 and higher-output groups also require the Turbo R conversion pump. Big-injector stages require a matched upgraded wastegate. Retain the factory turbo.

The tuning options describe the required installed setup. If purchasing cooling parts in this order, complete their installation before applying the selected calibration. Remaining screws, clamps, mounting and electrical connections must match your vehicle.

Set wastegate pressure and spark-plug gap to the delivered file’s instructions. Correct clutch setup is recommended to make use of the selected tune. Exhaust, clutch parts and other separately quoted build components are additional to the selected package.

Multi-map controls and upgraded-turbo builds require a separate build review and quote. Contact FastUTV with your hardware and fuel details.

Buy Can-Am cooling and conversion parts

Order genuine OEM parts from FastUTV at the regular retail/MSRP prices below. The year-matched cooling selector adds the chosen parts with your tuning package. OEM products are special order; delivery timing varies.

The 2018–2019 cooling kit and 2020 intercooler assembly already include a fan. A separate fan is offered only for an existing matching intercooler setup. The 2018–2019 kit also includes OEM hoses; WSRD tubes are an optional replacement for those hoses. For the 2020 assembly, choose compatible WSRD upper/lower tubing or OEM inlet 707800866 ($39.99) and outlet 707800867 ($114.99). The 2020 assembly with both OEM hoses totals $884.97, before remaining installation hardware.

OEM Power Upgrade Installation Kit 715007111 — $1,024.99 is available separately. This full factory conversion hardware package includes a fuel pump and clutch components as well as screws/clamps/ties. It is not a mounting-only kit and is not required in its entirety by the stock-pump SR stages. If this kit supplies your suitable conversion pump, select the tuning option without another supplied pump. The factory BRP diagnostic/OEM calibration procedure is separate from FastUTV tuning.

Regular retail and OEM MSRP checked October 6, 2026 against Can-Am’s current retail listing and manufacturer parts records. Supplier promotions and stock are separate from these FastUTV special-order products.

WSRD charge tube and blow-off valve

Select the WSRD silicone charge-tube package: choose the 120/135 HP intercooler-conversion upper tube with the lower tube, $228. Add the WSRD blow-off valve option for $249 more, making the complete upper/lower tube and valve selection $477. Match the tubing to your installed intercooler before ordering. The WSRD package is a separate product and can be selected with tuning in the cooling selector; it does not include an intercooler or fan.

Choose the 120/135 HP conversion upper tube with the lower tube, then select color and valve choice beside Add to cart. Only currently purchasable WSRD options are offered; its existing availability and backorder terms apply.
