Sea-Doo Remap Dorset | RXP-X GTI GTX Tuning

Sea-Doo's Rotax-powered lineup, from the supercharged RXP-X and RXT-X through to the recreational GTI, GTX and Spark ranges, is the most popular PWC platform on Poole Harbour and Bournemouth Bay. Factory maps are set conservatively for global homologation and drivetrain protection. 24Tuning delivers custom Stage 1 remapping for the full Sea-Doo range — on-board at your marina or mooring.

Why Remap a Sea-Doo?

Sea-Doo's Rotax engines are tuned for the widest possible market and drivetrain safety margin rather than outright acceleration. A Stage 1 remap sharpens throttle mapping and recalibrates boost on supercharged models within safe factory tolerances.

Quicker hole shot from standstill
Stronger mid-range for jumping and towing
Sharper, more predictable throttle response
Improved top-end on supercharged RXP-X / RXT-X models
Fully reversible with original map restore

Frequently Asked Questions

Which Sea-Doo models can you remap?

We cover the full current range including RXP-X 1630 (2024), RXP-X/RXT-X 1500, GTI, GTX and Spark 900 HO/ACE/Trixx. Confirm your exact model and year when booking.

Do you work on-board at the marina?

Yes. Our mobile marine engineers perform on-board ECU tuning at marinas, moorings and slipways across Poole Harbour, Bournemouth, Southampton and the Dorset coast.

Do supercharged RXP-X and RXT-X models see bigger gains?

Supercharged models typically show the most noticeable improvement, since boost and fuelling maps have the most headroom within safe factory tolerances.

Can the remap be reversed?

Absolutely. We back up your original factory ECU map before any changes and can restore it at any time, returning your Sea-Doo to completely stock settings.
