The principle of supercharging allows sea level pressure to be maintained to a higher altitude and sea level output can be maintained.

Explanation:
Supercharging raises the density of the intake air by compressing it, so the engine can keep a higher intake (manifold) pressure than the surrounding air at altitude. By boosting the manifold pressure toward sea-level values, the engine effectively sees nearly sea-level air density even when the aircraft is at higher elevations. This allows the engine to maintain horsepower close to its sea-level rating up to the altitude where the boost and fuel system can no longer sustain it. So both parts are true: you can hold sea-level pressure at a higher altitude, and you can maintain sea-level output within the system’s practical limits.
