So im thinking about going stage 2 on my 2016 WRX, installing both MA performance downpipe and intake with their stage 2 map, with these new mods I was curious if I needed to also install better fuel injectors and a fuel pump to avoid the car running too lean or should it run okay without a problem?

Nope, just install the MAPerformance intake and downpipe like their tune calls for. Anything else and you'd need a custom tune.
