JB4 Tune Question

Hey all I'm new to the BMW family as well as tuning.

I'm picking up my 335i this week and have been looking into the JB4 tune, just seems like a great product for an amazing price. I wanted to know if there was an optimal time to hook up the tune. With being such a new engine with less than 20 miles on it would it be ideal to wait past the break-in period or is it ok to plug it in right when I get home?

Thanks!
