You are unlikely to be at a disadvantage for the mere lack of a Step 2 score.
Options are:
Best: Take Step 2 early, have score that is comparable to, or an improvement on an already competitive Step 1 score on hand that goes on your application
Good: Take Step 2 just prior to interviews, although your score may not be available to programs, but be able to say, "I've taken step 2"
obviously not great: Take step 2 early and be unhappy with your score.
Your step 1 score is competitive. I think it should be sufficient to get you into a good Anesthesia program.
My Step 1 score was _ _ _s. That was sufficient.
I just happened to have Step 2 at the time as well (which was also _ _ _s). i don't think it made a huge difference.
Had your step 1 been <<220 with mediocre grades, then perhaps Step 2 (and a stellar performance on that) would be imperative
