Performance & Tuning specialists in North East
Overview
What performance & tuning usually covers
Bolt-on stages
Free-flow intake, upgraded intercooler, ride plate and intake grate, impeller matched to the target rpm, and a flash to suit.
Supercharged builds
Upgraded internals, bigger injectors and fuel supply, boost management, methanol or water injection where appropriate, and hardware to keep intake temperatures under control.
Handling and hookup
Pump wedges, nozzle changes, sponsons, hull rework and weight distribution — often more useful than another few horsepower.
Costs
How much does jetski performance tuning cost?
Cost scales with how much of the driveline is upgraded to survive the power. Ask for a staged quote and what service intervals the finished build needs.
Power is easy; reliable power is not. Supercharger rebuilds, ECU flashes, intercoolers, big-bore kits and pump work all interact, and a tuner who understands the whole package will get more usable speed out of a ski than one who only sells parts. Ask what supporting mods a stage needs before you commit.
Questions
What to ask a performance & tuning specialist
- What power level does my hull and pump realistically support?
- Will the build affect insurance, warranty or class eligibility if I race?
- What is the recommended service schedule afterwards?
- Do you dyno or GPS-test the finished build?

FAQ
Performance & Tuning — frequently asked questions
- Does tuning a jetski affect insurance?
- Modifications generally need to be declared to your insurer. Speak to the insurer before the work is done, because an undeclared modification can invalidate a claim.
- Is an ECU flash safe on a standard engine?
- It depends on the platform, the ski's condition and the supporting hardware. A reputable tuner will inspect the ski, check the supercharger and cooling first, and refuse work that would run outside safe limits.
