How accurate is stock boost gauge/sensor

[twin plugged targa]

How accurate is the stock boost gauge?
Mine is showing boost of 0.9bar in temps of around 45F
I just had a new pressure sensor installed - maybe that is the culprit?
Prior to that it showed around 0.7 bar which I think is more normal?
any info appreciated

PS I believe engine is stock

I have the stock gauge and I also have an aftermarket gauge in the clock location. Both gauges indicate peak (.9) bar pressures accurately. Not so sure off peak is the same.

Thanks- I thought a stock WG spring only took the turbo pressure to 0.7 bar?

I too have an additional gauge besides the stock one, and both seem to read the same or very close to eachother.
Stock boost is .8 bar.

will cold weather take the boost past the normal 0.8bar as she definately went to 0.9bar indicated!
Should I worry?
Or just continue to monitor
thanks
