However, I do agree with your advice that folks should consult with a reputable tuner to help them determine the correct injector size and fuel system modifications.

One way or the other you're going to need to upgrade your pump. My experience has been that upgrading the fuel pump raises the base fuel pressure to 52psi. YMMV. This will effectively increase the output of the stock injectors to approximately 605cc/min.
As you probably know, both fuel pump upgrades AND larger injectors require a ECU reflash to scale the fuel maps. I'm suggesting injectors and a pump upgrade at the same time since you can tune for both with one reflash and be done with it. Once you've flashed for the fuel system mods, pretty much all other mods are VE related can be handled by the piggyback of your choice, SAFC, UTEC, Xede or whatever.
