Ok... Stupid tablet wont let me upload right now.
Here are symptoms:

Idle:
Vacuum 18-20 in idle with no loss or flutter. Very smooth

Idle with throttle:
Moves around a little on vacuum side but no flutter.






PROBLEM IS HERE:
Low acceleration and some normal driving speeds:
Flutter in vacuum side as well as boost side






Mid acceleration: smooth operation to boost and all up boost to 15

Full WOT:
Boost builds smooth to 15psi and after new o2 sensor previous flutter at 15psi seems to have vanished amd car holds 15psi smooth.
