Modifications to 2018 Sea-Doo GTR 230


I have 2018 Sea-Doo GTR 230. I want to modify top end speed, living in Nor-Cal seems not getting any results. Can I get some expert know of how to from you guys?


Hey Law, welcome to the site.

What have you done so far to help along performance? Some common mods are listed below:

Solas Concord 14/19 Impeller
Sea Doo RIVA / V-TECH Maptuner X Tune Bundle
RIVA Sea-Doo RXP/RXT 260 & GTR 215/230 Power Filter
Fizzle SuperCooler for Sea-Doo 300

From there we can start talking about upgrading the supercharger and valve retainers and springs.
