Emissions

i removed my emissions a long time ago and i was just brosing through the forums because i was bored and looked at Igotverts post "read before asking" checked out the free boost mod that he has sited and i noticed that i removed all that junk that was shown on the site... thinking it was all emisisons... hopefully it is, and thats what im asking... i diconected everything that attached to my throttle body at the top and pluged it off.. ive come to understand that one was that boost and wategate controller... ummm could someone tell me what i need to hook up and what not...?
