ffs, the people who say baby it for the first 200 kms or so have no clue, this is the most crucial period for the rings to bed in, you risk glazing the bores or not getting a propper seal if you dont load up the motor straight away, likewise you should avoid idling and sitting on constant RPM.
best way to run the motor in is to use stock boost settings, and drive it hard through hills, that way the motor see's a varying rev and load range. If the motor breaks during this period, its a shit rebuild
