This competition ECU flash for the Ski-Doo 850 Turbo recalibrates your factory ECU to deliver up to 205 horsepower on 91 octane pump gas, with no wiring or splicing required. The plug-and-play flash is performed through your factory diagnostic port, and the package includes a lightweight muffler, charge and intake tubes, and a clutch kit with calibrations set up for the new horsepower level.

Built for 2024 through 2027 Ski-Doo 850 Turbo models, the tune sharpens throttle response and boost control while adding on-board diagnostics, fault-code reading, and live data logging you can run from your phone. Clutching adjustments are required if the included clutch kit is not installed.
