that is true, but if your making all kinds of upgrades, injectors would usually be the last piece to the puzzle considering you need to be tuned ASAP for them or your car will run so horrible. so for someone to put in 1000cc injectors then keep upgrading, is pointless

grey~ghost

my tuner said to not go over 850cc for my build, that anything over would be overkill for the ECU. im kind of confused at this point because i see people running 1000cc for similar builds.

im gonna be running 1200cc on a similar setup, but NO meth

with meth you can get away with running a smaller injector then you would for straight pump gas.

Ive seen many guys runing 1000ccs on stock ecu , used to myself no problems at all! now im running an .............Hydra

Stockers are fine. If you ever upgrade turbos, the two biggest things to determine what size of injector you'll need is airflow and fuel pressure. I have a little chart somewhere that has what injector size can keep up with how many lbs/min at 43.5psi base fuel pressure if someone wants to see it.
