Sounds like a classic problem of boost leakage. You get the same symptoms when one of the boots between the turbo and the throttle body pops off under boost.
Check the clamps on the rubber turbo ducting boots for looseness and check the rubber boots themselves for cracks and for signs that local rodents have developed a taste for oily rubber.
Also make sure that the rubber bushings that hold the vacuum nipples into the intake manifold haven't deteriorated.
