Anything that improves airflow through a supercharged engine should result in a decrease of boost pressure. If the engine can digest the air with less effort, the build up of air (pressure) in the intake manifold will decrease. This doesn't mean the supercharger is pushing less air into the engine. Its compressor speed is defined by its drive ratio to the crankshaft. So lowering boost via improved engine airflow will only increase power: reduction in pumping losses and parasitic drag and improved thermal efficiency,
