The charger physically isn't able to make the same boost at our altitude so nothing can be corrected that does not exist.
No charger will, but forced air loses less % of power at altitude than an NA motor. Turbos and s/c were actually designed for use in piston powered aircraft motors to still have power at flying altitudes.

Example; when I was in Colorado Springs, an NA car would lose about 18% horsepower when compared to the same NA car at sea level. A turbo car would only lose about 5% and a supercharged car about 4-5%.
