This bundle pairs a tuning cable that works with BUDS with one Sea-Doo VIN license, sized for 2018-2020 RXT-X and GTX Limited 300 (ST3). A stock ST3 300 typically reaches 79-82 mph depending on conditions.
Expect faster acceleration, sharper throttle with less lag, a higher RPM limit, mild touring-mode changes and dramatic sport-mode changes. No extra license is needed if you later add an intake or supercharger to the same machine. The Torx DIY intake adds 1-2 mph and low-end pull; a custom 4-blade 159mm Solas impeller adds another 2-3 mph.
- Fits 2018-2020 RXT-X, GTX Limited 300

- Stock ski: 79-82 mph
- No fee for later re-flashes
You will see this item under the 2020 Sea-Doo 300 GTX Limited section. Please confirm the fitment details above match your machine before ordering. Catalog reference: TORX-STG1-260-2-17.
