For CE, you want to be above the averages for all the schools in GPA and SAT scores. Also for the UC’s you want strong EC’s and essays to help boost your application. Your UC GPA is competitive, the SAT no so much.

Last years Average UC/CSU GPA/SAT (Math + CR) scores: You want to aim to be at or above and I am sure the averages are higher for this years in-coming class:
All Cal States except SLO use the eligiblity index to rank applicants.
