I wouldn't run it in too easy. I'd take it further up the rev range but obv not on full boost or the like. Just slowly wind it up rather than full beans, plenty gear changes early on rather than motorway driving. Some folk even disconnect the turbo to save being a bit keen to push on etc..
I sure it's along the lines of running in oil for the first 200 miles, ditch it for something else then nearer 700 miles put the good stuff in?
Im sure everyone will have their own way to do it Chris so perhaps a phone to an engine builder or feedback from someone who's just went through the same process would be the best idea for peace of mind and a good strong engine in the long run.
