In a supercharged engine, a leak in the inlet manifold causes loss in the inlet manifold pressure and mixture at high power settings, resulting in reductions in which two items?

When a booster is doing its job, the engine relies on high pressure in the intake manifold to push more air into the cylinders. A leak in the inlet manifold lets some of that boosted air escape, so the actual manifold pressure drops, especially at high power settings when boost is at its peak.

With less air being drawn into the cylinders, the air-fuel mixture becomes less effective. The fuel system tries to meter fuel based on the available air, so the mixture is reduced as well. That weaker mixture means combustion is less energetic and less efficient.

So the immediate effects are a drop in manifold pressure and a weaker mixture, which together lead to lower efficiency and reduced power output.
