Ultra 310X, Ultra 300X, STX-15F & SX-R Stage 1 calibration. On-board at your marina or mooring.
Kawasaki's supercharged Ultra range is the benchmark for outright PWC performance, while the naturally-aspirated STX series and stand-up SX-R serve recreational and freestyle riders across Poole Harbour and Bournemouth Bay. Factory maps are set conservatively for global homologation and drivetrain protection. 24Tuning delivers custom Stage 1 remapping across the Kawasaki range — on-board at your marina or mooring.
Kawasaki's factory maps are tuned for the widest possible market and drivetrain safety margin rather than outright acceleration. A Stage 1 remap recalibrates boost and fuelling on supercharged Ultra models within safe factory tolerances.
Coverage spans the supercharged Ultra performance range through to stand-up and recreational models:
| Engine / Model | Stock | Stage 1 (est.) | Gain | Notes |
|---|---|---|---|---|
| Ultra 310X | 310 HP | ~332 HP | +~22 HP | Stage 1 software |
| Ultra 310LX-S | 310 HP | ~330 HP | +~20 HP | Stage 1 software |
| Ultra 300X | 300 HP | ~320 HP | +~20 HP | Stage 1 software |
| Ultra 250X | 250 HP | ~267 HP | +~17 HP | Stage 1 software |
| STX-15F | 160 HP | ~171 HP | +~11 HP | Stage 1 software |
| SX-R 160 | 160 HP | ~172 HP | +~12 HP | Stage 1 software |
Figures are conservative estimates based on typical Stage 1 marine calibrations. Exact gains depend on engine condition, propeller, load and use case. Torque figures of 0 Nm from source databases are omitted.
