Sea-Doo GTX 300 Tuning: Comfort Model with Noticeably More Punch
The Sea-Doo GTX 300 is the comfortable all-round model of the 300 HP platform. If you want more punch here, you use the same staged tuning concept as the sporty 300 models.
The Stage Principle
The concept is built in stages. Stage 1 is done purely via software by flash, from Stage 2 hardware modifications are added, and in the higher stages up to Stage 3 the package becomes more extensive. This lets you upgrade the GTX 300 in clear steps to suit your own needs.
Matching Hardware
On the hardware side, the Titanium Retainer for Sea-Doo 300HP set relieves the valvetrain and is designed for higher rpm. In addition, the Blow Off Valve Kit incl. Charge Air Hoses for Sea-Doo 300 and the M-JET 4 Inch Intake System for Sea-Doo 1503 & 1603 Engines provide clean boost and more airflow, with the intake system explicitly supporting the GTX 300.
Software, Diagnostics, and Care
The software side is handled by the M-JET Flasher for Sea-Doo Vehicles, the diagnostics by the M-JET DIAGNOSTIC - Diagnostic Tool for BRP. For long idle periods, the M-JET CTEK Charging Adapter for Sea-Doo Vehicles is recommended.
Conclusion
The GTX 300 combines comfort with real potential. With staged tuning and matching hardware, the cruiser becomes a noticeably stronger model.
