Unlock more power and performance from your Polaris Inc. Sportsman 450–570 with our Mail-In ECU Performance Tuning. Designed for both work and trail riders, this tune delivers 6–9 horsepower gains, stronger low-end torque, and improved throttle response across the entire RPM range.

By optimizing fuel mapping and ignition timing, we help your machine pull harder off the line and maintain power under load. The factory speed limiter is removed, allowing your Sportsman to reach its full potential.

This mail-in service is simple—ship us your ECU, and we’ll flash it with our proven performance calibration based on real-world testing.

  • 6–9 HP increase over stock

  • Increased low-end torque for better pulling power

How It Works:

  1. Remove your ECU from the machine

  2. Ship it to us securely
