Unlock the full potential of your Polaris RZR RS1 with the Aftermarket Assassins Custom Tunes for Powervision 3 and 4. Designed exclusively for riders who already own a Powervision device, these performance tunes deliver exceptional horsepower gains, faster throttle response, and smoother power delivery across the entire RPM range. Every tune is crafted with precision using real-world testing, ensuring your RZR RS1 runs stronger, cooler, and more efficiently than ever before.

Each custom tune is optimized to modify essential performance maps for superior results while maintaining reliability and engine safety. You can expect significant improvements in throttle sensitivity, torque management, and mid-range fueling for a more responsive and powerful ride. The fan temperature settings are adjusted to 195/185°F for better cooling, while seatbelt and speed limiters are removed to let your RS1 perform without restrictions. With a raised rev limit of 9200 RPM, these tunes push your machine to new heights without compromising safety.

Available Tune Levels:

• Level 1: Ideal for stock exhaust setups, offering gains of 6–7 RWHP and up to 9 RWHP with an S3 clutch kit.
• Level 2: Perfect for slip-on or full exhaust systems, delivering 8–10 RWHP gains and even higher with clutch upgrades.
• Level 3: Designed for performance cam setups with optimized fueling and timing adjustments.
• Level 4: Tuned for big bore kits with specific fueling and timing calibrations based on your engine build.

For those running high-octane fuel (95 or higher), an optional hotter timing curve adds 2–3 RWHP and boosts low-end torque. These tunes outperform generic DynoJet maps by reaching peak timing faster, optimizing torque limiters, and providing a refined fuel curve for maximum power at wide-open throttle. The result is instant throttle response and consistent top-end performance.

Key Benefits:

• Improved acceleration and mid-range punch
• Instant throttle engagement without lag
• Customizable for tire size and riding conditions
• Enhanced fuel mapping for better efficiency
• Easy installation and downloadable tune files

Tunes are securely delivered via email within 24 hours on weekdays, and if you prefer, our experts can install them for you for a small fee. Each tune is password-protected to preserve proprietary calibration data, ensuring you receive industry-leading performance backed by expert engineering. Transform your Polaris RZR RS1 into a high-performance powerhouse with Aftermarket Assassins Powervision Custom Tunes—the ultimate upgrade for serious riders who demand more from every ride.
