I personally don't think we will need injectors till after 200+ WHP, throttle bodies haven't seemed to be a limiting factor so far, one of IE,s customers has cams and personally I won't open my engine, I'm doing strictly bolt ons.
I don't want to say what my car makes for power without having it on a dyno but I can say it feels very healthy. Especially after flashing IE's updated "header tune" today. My MPGs are higher since the header and the car overall just feels stronger especially with the new tune.
