Whether you’re running a completely stock setup or have supporting performance upgrades, these custom tunes transform your RZR into a high-performance machine that dominates any terrain.
The DynoJet Power Vision ECU tuner comes preloaded with Aftermarket Assassins’ exclusive performance tunes. Simply plug into your diagnostic port, flash your ECU, and experience instant gains in power and responsiveness. The Power Vision doubles as a live data gauge, allowing you to monitor boost, timing, and engine performance in real time, or remove it after flashing. With built-in data logging, diagnostic capabilities, and the option to return to stock at any time, this tuner offers complete control and flexibility for your RZR.
Each tune has been dyno-developed and trail-tested to ensure maximum reliability and safe power delivery. Depending on the level selected, you can expect horsepower gains ranging from +10 RWHP up to over 60 RWHP, with boost pressures reaching as high as 25 PSI. Advanced calibrations include raised speed and rev limiters, improved cooling fan engagement at 185°F, throttle-by-wire limiter removal, optimized fuel and timing curves, and optional start-in-any-gear functionality. These enhancements combine to deliver faster acceleration, smoother throttle response, and cooler operating temperatures.
Aftermarket Assassins’ proven expertise in tuning CVT-equipped UTVs ensures precise calibration for both power and clutch performance. Each tune maximizes the efficiency of your stock or modified turbo system, supporting mods such as exhausts, charge tubes, and upgraded injectors. Whether you choose a mild 91-octane tune for everyday riding or a high-octane race setup exceeding 200 RWHP, you’ll experience a dramatic transformation in your RZR’s performance.
Built for riders who demand the best, the AA Custom Tuned Power Vision is the ultimate plug-and-play solution for anyone ready to push their RZR Pro XP, Turbo R, or Pro S to its limits.
