Summary
Custom ECU tuning for the 2025 Sea-Doo GTR-X 300, calibrated by Lukos Engineering. The GTR-X 300 already punches hard for its size; a machine-specific calibration sharpens how that delivery arrives - response and consistency refined from your craft's data, not a file built for someone else's. Choose the tune with the tuning device included, or tune only if you already run compatible hardware.
Best For
- GTR-X 300 owners refining response for harder riding
- Riders who want their specific craft calibrated, modifications included
- Owners choosing data-driven work over generic flashes

Fitment And Setup Checks
Confirm your craft is the 2025 GTR-X 300 before ordering and mention any modifications. Recent Sea-Doo ECUs can require an unlocking step before calibration - check the requirements for your exact craft with us first so the process is planned end to end. Tune-only assumes you already own compatible hardware.

Frequently Asked Questions
Will my ECU need unlocking?
Possibly - some 2025 Sea-Doo ECUs require an unlock before tuning. Check with us for your craft before ordering.
Which option do I need?
Tune-only if you already run compatible tuning hardware; otherwise take the option with the device included.
Confirm the craft and let the GTR-X be calibrated around the way you actually ride it.
