Question if a 2000 Pontiac Grand Prix was switched from the standard 3800 engine to the Supercharged Version of the engine. Does the Firing order change or is it the same regardless for the 3800 Engine.

It stays the same.

Thank You, My car sounds terrible and I thought I had the firing order wrong when I put the wires back after replacing the Intake manifold gasket. But when I checked my VIN there isn't a 1 for the engine code there but the car has a supercharger. She still sounds terrible and won't run more than 5 minutes after starting and immediately shuts down when you try to put her into gear. I pray I didn't damage engine the day she died on me.
