Ultra Boost ECUs are sold, fitted and tuned through our authorised dealer network, not available to buy online. Your dealer matches the right unit to your vehicle and dyno-tunes it for the best, safest result.

Available units by vehicle

Each Ultra Boost is calibrated to a specific make & engine. Find yours below, then visit a dealer to have it fitted.

Ultra Boost is a tunable piggyback ECU that optimises the signals between your engine's sensors and the factory computer, lifting boost and fuelling within safe limits. Nothing in the factory ECU is remapped or overwritten, so the unit is fully reversible and leaves the factory ECU untouched. Four switchable maps cover towing, daily driving, economy and full power, controlled from the mobile app or the dash-mounted controller.
