Transform your Can-Am Maverick X3 135HP into a high-performance powerhouse with the Aftermarket Assassins 135HP to 220+HP Upgrade Kit. Designed specifically for the 2023 and newer non-intercooled X3 base models, this complete upgrade package delivers the power, reliability, and precision tuning your UTV deserves. Whether you’re tackling dunes, trails, or open desert, this kit ensures maximum horsepower gains and improved throttle response while maintaining factory-level dependability.
The Aftermarket Assassins X3 135HP to 220+HP Upgrade Kit includes everything needed for a seamless conversion: HP Tuners MPVI3 with ECU unlock service, OBDII to Can-Am diagnostic cable, preloaded tuning credits, custom AA ECU tune, oversized black intercooler with fan, AA wastegate (7–18 PSI kit), S2 clutch kit, blow-off valve, and high-strength charge tube with clamps. This combination allows your X3 to achieve up to 250HP depending on octane and setup while optimizing airflow, cooling, and fueling for consistent performance in demanding conditions.
Each tune level is engineered for maximum power and efficiency, with proven results through extensive dyno and real-world testing. Expect faster throttle response, raised rev limits up to 9000 RPM, improved torque delivery, and cooler engine temperatures with a fan engagement point lowered to 185°F. The ECU recalibration removes restrictive factory limiters such as speed caps, throttle-by-wire restrictions, and seatbelt limiters, giving you full control and smoother drivability across all gears and driving modes.
Installation requires sending in your ECU for an unlock service, after which you can flash updates anytime using a Windows laptop and HP Tuners software. AA’s advanced tuning technology ensures optimal air/fuel ratios, precise boost control, and safe timing curves for each octane level. With proper setup, the kit supports multiple stages from 210HP to over 250HP depending on fuel grade and supporting modifications like exhaust and clutching upgrades.
Built for enthusiasts who demand the best, this upgrade kit not only boosts performance but also enhances reliability through proper airflow management, data logging capability, and refined ECU calibration. Aftermarket Assassins’ years of tuning experience on the Maverick X3 platform guarantee unmatched power delivery, smoother acceleration, and real-world-tested durability.
