Default Squeeze the most out of factory injectors

Next thing on the agenda now that I have basically a straight through exhaust, custom intake and a boost controller, is to mod the fuel system, I am thinking a drop in DW300 pump and an adjustable fuel reg, but how far can I push stock Ej255 injectors on the 2011 JDM Legacy?

Your question doesn't really make any sense. If you're sticking with the VF54 and not running e85 then that turbo will max out the injectors. You basically told us nothing about what setup you plan on running, the direction of your build, and all the appropriate supporting mods you have and plan to purchase in the future.

One thing to note is talk to your tuner. Many tuners have preferred injectors they tune with. So unless you're tuning yourself (which I wouldn't recommend based on how you framed this question), then you should tell your tuner everything you want to do with the car and get what they recommend.

Injectors are cheap, trying to max them out is not smart.
