The workshop
EFI tuning for select four-stroke watercraft
BS Tuning works on a defined range of Yamaha, Kawasaki, and Sea-Doo four-stroke platforms. We focus on that scope so every reflash, device, and part is matched to the hull it was built for.

Calibration philosophy
Measured data over marketing numbers.
Every calibration is checked against dyno logs and real-world water testing. We publish what we can verify and leave out the figures we cannot.
Platform scope
Built around the hulls we know best
We concentrate on four-stroke standup and runabout hulls. Narrowing the scope lets us document each setup in detail, from fuel mapping to intake and exhaust changes.
Technical guides and setup notes are kept editable, so the information stays current as platforms and parts change. Start with the craft and its setup; the right tune depends on what you are working with.
