Stage 2 on a GTI peaks around 22-24psi. 32 does seem pretty high.
I think you have to subtract 14.7? Boost will also be lower if it's cooler out.
14.7 is atmospheric pressure so subtract that from what the gauge says.
You are getting this reading from the OBD2 port right? Most accurate way is from the intake manifold
Unitronic Stage 2 GTI is 20psi. Not sure what a APR Stage 2 R is suppose to be.
Is it cold outside? The ecu is set for torque target not boost target. When it’s cold out you will boost less because the air is denser so you need less of it make the same amount of power.
To check if it’s correct you can data log requested boosts vs actual and see if the numbers are close. If the ECU is requesting 24 and you are only getting 18 then you could have a leak somewhere. If the ECU is requesting 18 and your actual is 18 then all should be good.
Generally depending on how bad the leak is but if it was a progressive leak you may not notice it. You can hear them sometimes too. I have seen 3-4 psi lower then what I should on my GTI when it is cold out. If you do a lot of pulls it will start to go up as IAT's go up.
This is a little log I did just to play around with things but as you can see my specified and actual are pretty close to each other. I should peak at 18 but it was a cool night so it only requested 16.5.
