I just put a new motor in my Z28, When I reinstalled my turbo, I went from a 2.5" charge pipe to a 3" charge pipe. I now notice I'm not getting much boost. I have a small t4 turbo, think it has a 2" outlet. Could this be my problem or is it something else.

well it has to fill the void with more air because of the increase volume of the new 3" pipe, i would say do a boost leak check, if you're good raise the boost to what it was before
