Competition Lost Smoke

[DDarmos]

My truck quit smoking out over night, plus i lost about 4pds of boost. I just put in a new fuel filter that did not fix it. It will smoke a little when i start it up, but not when i get on it very little black and mainly what appears to be gray. Still moves pretty quick but not like before. Any suggestions? I don't know what the fuel pressure is.

Please help!
