Just my experience. I went totally contrary to what I was told. I was given a low boost map, around 7psi. I ended up switching my map to the Cobb stage 2 map because my idle was so low, the car kept shutting off. Anyway. I drove the car fairly normally. Revved to around 5500 rpm. Occasionally did some WOT pulls around 3 or 4 per day. Let the car decelerate on it's own. So far the motor runs great. Like I said, it's just my experience. If you search on line, I'm sure you'll find around 5 or more different philosophies on how to properly break in a new engine. I'm just suggesting that maybe you don't have to pussyfoot it around for 1,500 miles for your break in. Just a thought.
