I regularly see over 1 bar (about 15 psi) under load. It will peak at 1.4 bar if I jump on the throttle suddenly and then pull back to around 1 bar. Cruising I'll see around 0.4 bar.

The setpoint is what the ECU requests.
You can also read it with Torque Pro (easier to see the maximum values). I recall seeing spikes of 20-21 PSI, so just in line with JeanLuke's readings.

Boost gauge. Sits at about 5psi at 100k.
Stand on it an it'll go over 20psi until the solenoid cuts the vacuum, then settles back to about 15psi.

i think i have an overboosting problem, or a bad sensor, mine goes just over 30psi. but the boost setpoint match with the 30 psi, so i'm confused.(i read it with jeep diag pro)
what's your boost pressure at idle?
