I have a distinct moan that happens when I decellerate between shifts ( I have a 5 speed)

The sound seems to be coming from the air box / turbo area ?
Its only when I let off the accellerator and the engine RPM's have dropped down , then it goes away. No performance probs.

I have 220K mi on this rig.

HAs anyone else had this problem .

Waste gate noise ? turbo noise ?

Any ideas ?

Mine makes a sound that sounds like what your describing, but mine is just the turbo when I shift my 5-speed. Sorry, no help.
