About Sea-Doo 300 tuning
We tune the Sea-Doo 300 in 2 applications across the Fish Pro APEX, GTX, from 2025, in gasoline form. Calibrations are written on HP Tuners for your exact hardware and fuel, then proven on our Dynojet 424xLC2 in Jenison, MI. Remote tuning is available for supported applications.
