Ok... Stupid tablet wont let me upload right now.
Here are symptoms:
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
Boost builds smooth to 15psi and after new o2 sensor previous flutter at 15psi seems to have vanished amd car holds 15psi smooth.
