Larger New turbo, No Boost
 

alright guys, i searched but didnt find much so now im turning to you guys to hopefully help me out. i recently bought a new turbo and replaced it with my ts04 that needed to be rebuilt. well after installing and everything was nice and tight i started her up and she was idling fine and then after cooling down to running temp. i took it out and there's no boost, my gauge wont go over 0. Vacuum is at -16 and then i drive it but no boost. the first time i reved it up i heard BOV but now i hear nothing... i checked lines everything looked fine.. could limp mode be a possible answer? thanks guys i appreciate any help you offer.
