MAP is manifold absolute pressure. kPa is kilopascals.
That 101 kPa is the normal atmospheric pressure, which is 1013.25 millibars, or 101.325 kPa, at sea level.
If that value remains the same, no matter how hard you rise the RPM, then it is a problem. If it increases, then it's OK, as the turbo is doing its job.
When turning off the engine, the electric throttle is closing shut but the engine is still turning, generating some kind of vacuum into the intake manifold, hence the 50 kPa. Pressure that later returns to normal, atmospheric pressure.
So normal operating values.
