What size injectors are you running? If they are stock and the fmu disk is stock I would say you don't really need one. Of course the next mod I would do would be 42lb injectors, MAF, and an afpr. I'm not a fan of FMU's, there slow and sometimes don't react fast enough. Don't be scared of large injectors, the new lightning comes with 42's. This would allow you to grow and you wouldn't have to worry about fuel problems for a while.
