you may have a waste gate on your turbo the spring in the gate may be weak. check your air filters they may look ok, but if there old they will restrict flow when the paper starts to break down. bad fuel filters or a partally blocked line can produce the same results.
good luck..

Look at your air fuel ratio diaphagm on the back of the fuel pump. should be a air line coming from intake to it. If that diaphagm is ruptured, It will not increase fuel to the engine as boost increases. Parts are aval. though Cat dealer for $20.00. About 30min to change
