When breaking in a new motor, you are not suppose to get on boost for about 500 miles and keep the rpms below about 3000. Then you slowly over time increase the rpms and use boost until about 1000-1500 miles.
Almost any GOOD map will be fine up to about 5psi boost, but if it has never run in your car, you might have idle and cruise problems if not specially tuned on your car for your engine.
You do not say anything about your map being used for your engine before the rebuild.
If they are hungry, send them pork.
