UMich is no safety for anyone particularly from OOS. The OOS admission rate this year is at 20% or below. For OP interested in Computer Sci or other science area, UMich LSA would be a good option and it should be a high match to match. Your SAT1 and GPA are great while SAT2 is fine. It is not uncommon to reject near perfect score applicants at UMich if you look at the chance thread there, but you should be a strong candidate. It is just the admission rate for OOS students that it is hard to make it a low match.
