Retake or no?

Just got my August LSAT score back, got a 170. I'm a D1 athlete, have a 4.0 GPA, and a decent resume but I'm shooting for Harvard, Yale, or Standard. I'm an URM but I'm also applying straight out of undergrad. My highest score on a PT was 176. Should I re-take the LSAT in September? Any advice is greatly appreciated :)
