falls on face at boost

when i am coming into boost she falls flat on her face and doesnt boost at all. I did put new injectors in which are the 440's which is factory size. Only thing i could think of is the fuel mapping. I do notice its sucking lots of gas too. any suggestions

all of your connedctions tight? clamps tight?
haha have a lil hole in my manifold and was getting lower boost then normal.. then 3 days ago all of a sudden its boosting hard :lol: now and i havent done a thing
