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.
