Boost is not electronic... it is strictly mechanical if your car is stock. If you are blowing exhaust you are spinning the turbo. 0.6 might be all that your old waste gate spring will hold. 0.7 is the actually reading I was getting out of my stock spring, so 0.6 is not that far off.
Does the car feel like it is not making boost when you drive it? You should be able to tell from your butt dyno.
The gauge should show vacuum at idle so that is correct. Are you only having a gauge issue or is the issue with the drivability of the car?
