I have 1 mp40 in my 90 gallon tank do you think I need another mp40 for the other side ?

Depend on what you will host. It can be enough though I would prefer 2, one on each side...

As OH suggests, the issue is one of turn over volume. Divide your flow rate (gph) by the gallons in your DT. Different types of corals will require different turnover.

ecotech have a nice online tool that can show you the flow requirements based on your system dimensions.
