I had it on the floor when it lost power at 4,000 RPMs and sounded like it was missing on one cylinder. I limped it home and started it the next morning and it was firing on all 4 but still didn’t have the power.

This can be the timing chain that has jumped time or the boot between the supercharger and intake manifold is blown, do you have a check engine light on? Even if the answer is no, we should run the codes to see what comes up.
