Professional Remote Custom Tuning — From Anywhere
Get your Sea-Doo professionally custom tuned by Ruthless Racing without bringing the ski to our shop. Using the included HP Tuners RTD device, we can remotely tune your ECU, review data logs, monitor AFR and make revisions based on how your actual setup is performing.
Package Includes:
- HP Tuners RTD tuning device
- Ruthless Racing custom ECU calibration
- Stage 1, 2, 3 or 4 tuning
- Remote data-log review
- AFR review
- Tune revisions based on logged data
- Read & clear diagnostic trouble codes
- Remote tuning through the HP Tuners/TDN system
Compatible with 2016 to 2023 Sea-Doo 300 models including RXP-X, RXT-X, GTX and GTR applications.
Whether your ski is lightly modified or running a complete performance setup, your tune is built around your actual modifications and data — not a generic one-size-fits-all file.
