The Sea-Doo Switch is a pontoon-style platform rather than a performance model, but that does not mean the factory tune is the final word on how it feels to operate.
Where a Tune Helps Most
Throttle mapping at low speed, which matters a lot when docking or maneuvering near other boats, is one of the most noticeable areas a tailored tune can improve on the Switch.
Applying It Yourself
The M-JET Flasher lets you reflash the ECU directly, adjusting the map to suit how you actually use the boat instead of the generic factory setting.
