What is a PCM?

A PCM is a reprogrammed engine control unit, also known as a powertrain control module (PCM). It tunes the Grand Am computer for better performance.

There is also software available that allow the driver to tune the Grand Am computer more specifically for better performance, though this is only recommended to people who know what they're doing.
