KA-T boosting problem

Ok the car ran fine for a long time now.I get in and go to work On the way I relize the car is bucking under part thottle just starting to hit boost.the boost gauge was jumpy as it bucked and the turbo made some funny sounds like compressor surge while boosting.(running no blow off valve rite now,so I now what it sounds like.)now if I stab it hard it will move and make boost fine about 80% of the time......iv swaped out the mafs,map sensor and ran all new vacuum lines and made shure all the clamps are tight,my vacuum reads 20 at idle????anyone...oh and the turbo is 6 months old.
