Default Lq4 Injector sizing

I'm getting ready to put my Lq4 swap in, but need to wrap up some loose ends (fuel system etc). Right now its a stock lq4, TSP Tsunami cam with TSP rods and PRC springs, with a set of headers. I plan on running nitrous on it as she is, but need to figure out if I have enough injector.

So, will my stock injectors be enough for just the motor/cam combo? and should I consider going with larger injectors for the future, even if Im within the duty of the stock injectors? I'm going to be running twin 43gph pumps, and I'm using the truck manifold with built in regulator.
