Injector Q's?

I have recently installed a 75mm BBK throttle body and ported plenum, I also have longtubes O/R H-pipe.....my question is my car going to be running lean or rich? If it is running lean can I drop in some 26# injectors and richin it up a bit? I have a 75 shot of N2O, but about to pill up to 100....what do I need to do?
 
Just a retune is all you need because the stock injectors are good to about 300RWHP. I'm assuming you're talking about a wet nitrous kit. The nice thing about them is you don't need to screw with your injectors. :nice:
