6.0 no boost sounds like missing also

I have an 05' f350 stock everything w/ 120k. It ran good when I bought it but after putting about 3k on it the truck has no power when cold and the boost gauge is 0. Usually after it warms up the engine smooths out, the boost meter starts showing 20 plus boost and it runs perfect. I am thinking if the injectors are bad it wont build enough boost, then the bad ones start working and it goes to running good. What do you think?

I know it won't have boost at idle but when I drive truck even w/o a load on it should still build up some boost and it won't. i am just wondering if it is from 1 or 2 injectors not firing properly. I tried another one of them turbo boost solenoids on turbo and it didn't help.

I think the VGT parts are coked up. I had that problem on a 2003 so bad that Ford put a new turbo on it. It couldn't get out of it's own way. Once the engine warmed up it starts to free up a bit.

There is a procedure for removing the turbo, breaking it apart, cleaning, and reinstalling it. It works wonders. Unless the turbo is too cooked to get clean. I just got done doing a turbo for a 2004 E450. It was pretty messed up, far worse than what Ford would just throw away. I cleaned it anyway, and it seems to be working pretty darned good.
