Stage 3R MULTIMAP – From Race to Trail Up to 300 HP on 91-Octane Pump Gas The Precision EFI Stage 3R is our best bang-for-the-buck stock turbo performance package, combining incredible horsepower, outstanding drivability, and exceptional value. Originally developed as the ultimate stock turbo drag racing package, the Stage 3R quickly proved itself to be just as capable on the trail. It delivers explosive low-end torque, lightning-fast throttle response, and relentless acceleration while maintaining the reliability and rideability that Precision EFI is known for. If you're looking to maximize the performance of your stock turbo without compromising everyday usability, the Stage 3R is the perfect choice. Power at Your Fingertips The Stage 3R gives you complete control over your sled's performance. Thanks to the included Dashboard Reflash, you can instantly select different power levels directly from the factory controls—no laptop or reflashing required. Choose the calibration that best suits your riding style, with available power levels ranging from approximately 250 HP up to 300 HP on 91-octane pump gas. The package also includes adjustable Launch Control, allowing you to quickly set your preferred launch RPM for consistent starts at the drag strip or maximum fun on the trail. Built for Long Trail Days The Stage 3R isn't just about making horsepower. Our engineers spent countless hours optimizing the calibration to improve combustion efficiency, throttle response, and drivability. During normal trail riding, many customers experience better fuel economy than the factory calibration, despite the significant increase in performance. For long-distance rides, simply select the included Economy Map. Designed specifically for extended trail adventures, it delivers excellent fuel mileage while still producing noticeably more horsepower and torque than a completely stock sled. It's the perfect combination of performance and practicality. Precision EFI Knock Protection Every Precision EFI ECU calibration includes our proprietary Knock Protection System, continuously monitoring engine knock to maximize performance while protecting your engine under varying fuel quality and operating conditions. Kit Includes Precision EFI Stage 3R ECU Reflash Precision EFI Dashboard Reflash (Multi-Map) Precision EFI High-Flow Air Intake Precision EFI Upgraded Fuel System 4-Bar MAP Sensor Recommended Upgrade Blow-Off Valve Upgrade (strongly recommended) for improved boost control, turbocharger longevity, and maximum reliability. Clutch Calibration Required To achieve the advertised performance, the Stage 3R requires adjustable primary clutch weights. Maintaining the correct clutch calibration is essential to keep the engine operating in its optimum powerband, ensuring maximum acceleration, peak horsepower, and excellent belt life. The recommendations below are intended as a starting point for sleds equipped with a stock primary spring and helix in good condition. Final calibration may vary depending on gearing, snow conditions, elevation, rider weight, and other performance modifications. Target Engine Speed Target RPM: 9,000 RPM Clutch Adjustment Procedure Perform a full-throttle acceleration while applying the throttle progressively to minimize track spin. Once engine RPM stabilizes, record the maximum RPM. If engine RPM is above 9,000: Add clutch weight. If engine RPM is below 9,000: Remove clutch weight. Repeat the process until the engine consistently reaches 9,000 RPM under full load. Because snow conditions, temperature, altitude, and track traction all influence clutch performance, minor clutch adjustments may be required throughout the season to maintain the target RPM. The Perfect Stock Turbo Performance Package The Stage 3R has become one of Precision EFI's most popular packages because it offers everything performance riders are looking for: up to 300 horsepower on 91-octane pump gas, multiple dashboard-selectable power levels, adjustable Launch Control, excellent fuel economy, and the proven reliability of the factory turbocharger. Whether your goal is to dominate at the drag strip or enjoy hundreds of miles of aggressive trail riding, the Precision EFI Stage 3R delivers the perfect balance of performance, reliability, and value—all while keeping the engine operating at its ideal 9,000 RPM for maximum performance.
