Evolution Powersports - Can-Am Maverick X3 / X3 MAX Turbo RR P43R-325 Turbo Upgrade with MG1 ECU Unlock & Flex Fuel CodeShooter Power Flash

A first-of-its-kind, plug-and-play factory ECU implementation of Flex Fuel for the Can-Am Maverick X3 Turbo RR.

Gain 120+ wheel horsepower over stock tune on E85. Ethanol fuels provide increased knock resistance and superior heat removal from charge air, allowing for higher boost levels and optimized ignition timing for safer, more powerful performance.

Prior to EVP Flex Fuel, customers faced two major challenges: purchasing E85 by the barrel from suppliers or searching for gas stations with consistent 85% ethanol content. Fuel stations often sell "E85" with ethanol content as low as 45-50%, which causes running issues and potential engine damage when your tune expects 85%. EVP Flex Fuel solves this by allowing the ECU to automatically compensate for ethanol content ranging from pure 91 octane all the way to E98 (98% ethanol).

EVP combines an advanced ECU strategy with a GM flex fuel sensor and EVP control module that reads fuel ethanol content in real time. The system automatically adjusts tuning for optimal power and safety. If you blend fuels—such as pouring 91 octane into a tank half-full of E85—the tune adjusts automatically for the new ethanol percentage. Fill up at any E85 station or use standard 91 octane pump gas; the system handles it all.

• If the ECU loses connection to the EVP Ethanol Control Module, ignition and boost tables reduce to Stage 3-91 tuning while maintaining the last known ethanol content, keeping your engine safe and running.
• Built-in protection against erroneous sensor signals or rapid ethanol content changes; power returns to appropriate levels once errors clear.
• OEM MPH gauge displays fuel ethanol content when the headlight switch is pressed down.
• Check engine light alerts you to any system issues.

Most 91 octane fuel in the US contains 10-15% ethanol, which allows approximately 15 more wheel horsepower than straight 91 octane. EVP Flex Fuel takes advantage of this by incrementally increasing boost and ignition timing.

• First stock ECU implementation of flex fuel for the UTV industry
• Eliminates hassle of running E85 or ethanol-based fuels
• Maximizes power for any given ethanol content percentage
• Runs pure 91 octane gasoline through E98 (98% ethanol)
• Ethanol content displayed on OEM gauge cluster via headlight switch
• No wastegate adjustments required after initial setup
• Kit Includes: P43R-325 Turbo System, CodeShooter Power Flash with Flex Fuel, Flex Fuel Assembly, Blow Off Valve, Charge Tube Kit, V-Flow Intake Kit, Race Intercooler, Plenum Reinforcement Brace, Fuel Pump Kit, Injectors, Head Stud Kit, Spark Plugs, Fuel Injector Adapter Kit, 4 Bar MAP Sensor Kit

Dyno Note: Due to the MG1 ECU torque strategy, boost figures represent maximum boost on a hot engine. Cooler intake temperatures result in lower boost but the same power output. The ECU maintains consistent power by adjusting boost as intake temperature changes.

The P43R-325 turbo kit combines advanced aerodynamics on compressor and turbine wheels, a ported compressor inlet, and ceramic ball bearing CHRA for the most dominant turbo system available. This kit produces 325 crank horsepower on E85—approximately 125 more than stock—with instantaneous power delivery thanks to quick spool design. The turbo has overhead to reach 420+ crank horsepower with engine build and supporting components.

The kit reuses injectors and fuel pump from EVP's 2021-'23 X3 big injector packages. Only head studs, plenum clamp, race intercooler, and clutching are needed to complete the installation.

• 43mm (Red) compressor with 66mm turbine for big turbo flow capabilities
• Includes fuel pump kit
• Compatible with EVP MG1 adjustable launch control upgrade, plus boost and AFR dash readings
• OEM-style exhaust manifold bolts directly to engine with no modifications required
• EVP race turbo compressor cover with billet insert and anodized compressor wheels
• Ceramic ball bearing CHRA for instant spool, long life, and durability under extreme boost pressure
• Ceramic-coated exhaust housings retain exhaust energy for improved turbo response and reduced heat output
• Turbosmart wastegate actuator with easily adjustable turnbuckle

Important: Clutching your vehicle is mandatory with all EVP turbo systems. It is your responsibility to ensure proper clutching requirements are met.

2021-'23 Can-Am Maverick X3 Turbo RR models only. Also available for stock turbo applications.
