The fuel and ignition curve is optimized for 89 octane (95 EU for outside North America) or better fuel, Torque limiters are raised to a safe level. Electronic throttle bodies are controlled to allow 100% air flow when present. Often manufacturers will use the exact same engine for multiple horsepower models and simply detune them for the lower HP models. This allows Outboard EFI to easily get to the max HP and slightly beyond.
