6.0 no boost! help!

i have a 2003 6.0 powerstroke. it has no mods except for 4" exhaust. i was driving down the road yesterday and all of the sudden when i bring the rpms back up, theres no sound of turbo, and no boos ( i have an electronic boost gauge) there are no codes, or anything. last night i undid the EBP sensor, and blew it and the pipe out with compressed air. i also did the same with the MAP tube, sensor, and nipple hat goes into the intake manifold. didnt change a thing. made sure all the boots are tight, everything.! the turbo doesnt cycle on idle, alls you hear is "gargle gargle" engine also runs perfect, except for the lack of a turbo. when i look at my turbo from the intake side, it looks clean as a whistle. the blade spins freely. also when i am in high rpms i can slightly hear the turbo and it makes a whopping 1 pound of boost..thats it! before this happened i could make 25 ibs max! there were no warning signs to this. it was all of a sudden. i am leaning torwards VGT silonoid? somone help!
