Turbo Boost Dropping.

what would cause my boost to drop from 17psi down to 15psi under full throttle, besides lose connections and such... old hoses? anything to do with the fuel pump or FPR? anyone with answers lets here them, or could it be the gauge itself? I would think not because the car does fell slower then usual. all help appreciated...

wouldnt be the boost controller, im suspecting a boost leak as well. I guess its time to buy some new hoses/ boost lines for the car...
