Aftermarket Assassins '21 Can-Am Maverick X3 RR 195HP Stage 3 Lock & Load Kit w/ RTD4 ECU Unlock

Aftermarket Assassins '21 Can-Am Maverick X3 RR 195HP Stage 3 Lock & Load Kit w/ RTD4 ECU Unlock

This Stage 3 kit is designed exclusively for 2021 Can-Am X3 RR models equipped with the MG1 silver ECU and 6 arm primary clutch. It delivers a major increase in horsepower and torque through a combination of ECU tuning, clutching, exhaust, blow off valve, and catch can. The ECU tuning provides power gains based on tune level, supporting modifications, and fuel type, while clutching improves RPM ramp-up and helps reach higher RPM where optimal power is achieved. The exhaust reduces heat and back pressure, allowing more consistent boost, while the catch can and blow off valve ensure proper crankcase ventilation and turbo protection under higher boost conditions.

The 2021 X3 RR already offers strong performance, but this kit enhances boost response and maintains power at higher RPM where the factory setup falls off. ECU tuning improves boost delivery, allowing quicker spool-up and better boost retention past 8000 RPM. This system also enables ECU flashing, data logging, and diagnostics, making it a complete performance solution with both power and control.
