@profile427 there are more factors that will go into this than just your LSAT score. For example if you are a URM then your GPA would give you a shot at most of the T14 even with a 160. But of course, higher is always better!
Admission with those numbers is not unheard of, but very unlikely especially for a non-URM candidate. Odds are you won't get into any T14 with those numbers, though T20 is a reasonable bet. If you're okay with that, fine. If not, retake.
A 166 is far from a "weak score." You can get into many respectable law schools with that score (some even with $$). For example, My friend, who also earned a 166 was admitted into Emory (19th) with a $60k scholarship.
