    Fuel system upgrades needed for stage 2? ( 2012 WRX )

    At what point is it required to go with a better fuel pump and fuel injectors?? I have a 2012 WRX sedan daily driver and throwing on some upgrades like a Cobb intake, catted downpipe and catback, Perrin TMIC, Grimmspeed EBC and MBC, and the Accessport V3. If just sticking with the stock turbo and put these on, will the stock injectors and fuel pump be good enough to handle them? And if they aren't good enough, what would be the recommended pumps and injectors to get?

    From my research after a basic stage 2 setup you will need to upgrade injectors and Fp.

    you don't need fuel upgrades with those mods, your wasting money too. tmic is pointless until you do headers

    DW 65c pump is a good one, or a walbro 255 I believe.
    No idea about injectors because you don't need them yet. My future tuner said I'd be fine with stock injectors right now, but will need to upgrade them after ELH, tgv deletes, tmic and supporting mods. ..
    The fuel pump is just a nice safety feature. Its only 150 for the kit and it can be a DIY job.
    My project next week, and I'm a novice.
    Good luck!
