I leave my OBD dongle plugged in as long as it isn't more than a couple days without driving. Although my start/stop button doesn't react like you're describing. Not sure what to say about that.

In the Vehicle Profile, some things that may impact boost accuracy include:
Engine Displacment of 3 litres, Volumetric Efficienty of 85%, and Boost Adjustment of 0. Try playing with those values. I see "peak" levels of ~28-29 psi (it leaves a little red mark on the dial display where the peak occurred) at full fueling and high rpm's.
