I put a BMS PBX on a week or 2 ago, and I have noticed something after rather spirited drives, when I come home and park my 330i after these drives i notice the cooling fan stays on for 2-4 min.

This does not happen all the time, just after i drive aggressively. I have never noticed this before the Install of the PBX.

Is this normal? I just want to make sure that i am not over heating anything, rather make sure than have a warped head or something to that effect.

It was always happening, youre just driving more aggredively with the pbx so it stays on longer.

Normal. The electric water pump will stay on for a couple of mins to cool down the motor after spirited drives. This always happens to me when I visit a friend that lives on a hill top, near the end of a very twisty road.
