I am just a lowly med student, but what I have heard is that no matter the board score, it is good to take step 2 early and have it on your application. There are a few reasons for this:
You can to your step 1 score if it is low to average, it shows that you have confidence in yourself (a good quality for a surgeon), and it shows that you have clinical knowledge as well as basic science knowledge, which in most people's opinion is most important than basic science knowledge, if you had a high step 1 score - you show them that it wasn't a fluke, it also shows you to be a hard worker, because you're going to study harder for it if you know it's going to be on your app.
If I was looking at an app, and the person didn't have their step 2 score on there, I would think less of them because they were afraid to take it. Maybe they think they don't have a good clinical knowledge base or they themselves think that their step 1 was a fluke.
I made a 244, but I definitely plan on taking it in July. Again, just the opinion of a med student so take it for what it's worth.
