1 bar spring yet 12.2 psi on plx boost guage

Its not quite reaching 1 bar right. Spring is 1 year old. Is that normal?
Also on idle guage reads 1 to 1.5. I assume vaccuum in mmhg.. Is that a normal reading too?
Thank you

Was the guage accurate before the spring was installed?

Only had stock gauge when spring installed now have the plx boost gauge. Im hoping its correct as I want to be sure im at least .8 bar but not over 1 bar.
I just dont know how accurate they are. My original boost gauge in the speedo goes all the way to 1 bar though....

No.. Even with stock spring it went past .8 sometimes to 1. So i installed this digital one hoping to get a real reading but it seems im boosting to just over .8 bar. Not near 1 bar eventhough the spring is 1 bar

This is confusing. So the stock spring gives more boost than the aftermarket one?

With stock spring and stock gauge reading was .8 to 1 bar
Then i put 1 bar spring.
Stock gauge just went straight to 1 bar, but had no way of knowing if i was going further than 1 bar with stock gauge so I got Plx gauge and full boost shows 12.2 to 12.6 psi which i belive is just a little over .8 bar.
Im wondering if plx gauge is accurate

I know over boost switch works cause i lived it after a minor mixup connecting wastegate hoses. So i know im not boosting to or past that limit
