EDIT: I am assuming the 2004 models are the same as the 7.3 years where the VSS is located in the rear differential. If this is not correct, then someone should be along shortly to let you know where it's located.

turbo want boost
i have a 2004 power stroke 6.0 the turbo want boost until you reach about 3000 rpm
any ideas on what to do.
someone told me:
that the computer should be re programed.
that the blades could be sticking (need ro run it at a high rpm to sling the carbon build up off of the blades.)
it does not report any codes and you can hook a computer to it and make the turbo kick in
any ideas on what to do.

Recommend starting by reading the ABS codes. Without knowing what is triggering that ABS light, you are shooting in the dark. Once you have the error code deciphered, you should be able to isolate the problem.
From your description, I would suspect the rear sensor. If the code supports this guess, replace it and go from there.
The turbo lag issue is a totally different problem. Sometimes just using the truck under varying loads frees up the turbo's unison ring and things run normally afterwards. Worst case is a turbo cleaning.
