I currently have 2 PP-8 on my 4x4x12 and have been thinking about getting a gyre the tank is center overflow would it be okay back wall center or is my overflow going to disrupt everything

Trial and error is your best answer. Everyone’s tank is different and the flows they’re trying to achieve is different, but i usually put mine on the side walls facing each other, but that’s because i use vortechs
