I would also say emissions/ECU related. Driving other turbo cars (older, or custom) this does not occur, so any pressurization of the turbo, etc...makes no sense.

If the throttle plate is close, there is NO WHERE for the the air to go, except out a bypass valve

If the idle cotrol circuit was to open for a split second, squirt a smidge of fuel...
