The stock gasket between the supercharger and the throttle body is made conservatively from the factory to seal properly on every car. The problem with this is that you get an ever-so-slight overhang of the gasket into the airflow path.
To fix this simply remove your Throttle Body, being careful enough to reuse the old gasket or better yet buy a new one. With the Throttle Body off, you can then install the gasket onto the studs sticking out of the Super Charger. Then with a razor or trim knife, trim the gasket material that overhangs the Super Charger inlet.
Carefully put the Throttle Body back on the engine.
