Install a sport exhaust pipe, plug-in the MaptunerX a let it reprogram the ECU, combine this with a clutch kit and that's all you need to do to get the very most out of your Ski-Doo E-TEC 850 with our Stage 2 tuning software. Calibrated for the northern climate, tested by our ambassadeurs and carefully refined using all our knowledge in snowmobiles and engine management. For the person who wants more power than our Stage 1, the Stage 2 gives the Ski-Doo even more power and torque across the entire RPM-range by replacing the stock exhaust pipe with a sports pipe.
Our main focus is always overall drivability and ”accessible performance” at any time, instead of just peak power.
No Speed Limitation
Tune RPM Limit: 8300 rpm
