I think people over-exaggerate not boosting while breaking in the engine. You should boost here and there, have a few WOT pulls, and just overall have fun with the car. There's a difference between occasional spirited driving during break-in, and beating on the car.
Have fun with it and dont be scared to boost, I have 300 miles so far and have done a few redline shifts.
