Mine doesnt unless the engine is under load,
For example flat road in 1st and 2nd would peak around 12-14psi but on a nice hill would peak 16-18psi.
3rd and 4th would peak around the 16-18psi most the time to be honest.
That sounds a bit more realistic, I am also measuring from when on boost as in 0
idle mine is -8psi, boost is as said above
At idle mine is on 18-20 but that is at the bottom of the boost gauge, if you know what I mean. Not sure if that bit is measured in psi though
