Superchargers do nothing until the throttle is open at least half way…Less throttle than that and you are running intake manifold vacuum and the blower is not in the picture.
However, GM designed the puffer as part of the engine so simply removing it, while possible, would require major plumbing changes to get the belts and air-filter hooked up properly…Using the hardware from a similar but not supercharged model would simplify the process and would require a few hours in a salvage yard rounding up the parts you will need…
