[sinisa]

this may be very basic but people explained it when turboing with fmu or sfmu so i need to be sure. do i need afpr with MS, or stock fpr is sufficient if i choose my injectors wisely?

Fuel injector and fuel pressure go hand in hand. This calculator should help you.

What is your plan? To stay N/A or to turbo it?

If your staying N/A the stocker is fine.

If your going turbo you will want a 1:1 AFPR. The fuel pressure needs to rise as the boost rises otherwise you will have to hold your injectors open for longer at higher RPMs which will not be desirable.
