There is no limit, because the computer just uses pulse width to control it. It doesnt think "i need XX cc's of fuel"

Theres people on this site using 160lb injectors, I think you'll be ok.

To go to a low impedance injector, would you need to change the injector drivers like I had to do with the old ECM in my GN?

Not a new PCM, but external drivers.

Your factory pcm will control any high impedance injector(if you reflash the pcm). With that said the biggest high impedance injector is 72 lbs/hr. You can run a low impedance injector, you will have to get a external driver (AEM,Big stuff 3, etc.)
