  Symptoms are classic for a failed TBV (turbo bypass valve) to me. Check 
Scott M's site regarding replacement. Not too expensive and quite easy to 
do. 

Regarding likely fuel pump noise-- when in California in warm conditions 
(~90 or better), our pump buzzed as well. I believe it's their gas mix down 
there, as symptoms disappear up in the Oregon/Washington area. I've heard 
some have tried adding a small amount of auto trans fluid to the tank to 
help lube the pump. 

good luck.
