Hello, my car started throw black smoke and sometimes get choppy. I tested my turbochager and these readings are normal?
Car power still good.

It's going to be rather difficult for anyone to interpret that graph without seeing a scan of the car to know what ECU you have, and without knowing which MVB that data is from.

By the looks of it, it's the specified/actual readings for the boost at idle, which is going to prove nothing. The black smoke under load would either presume too much fuel or lack of air (boost leak) both in turn could be described as the same thing.
