Hi there, I have appeared for SET, and according to last year's counselling rounds, 86 might not be enough to get branches like Computer/IT/ECE. However you may get Mechanical,Civil,etc. Check out the schedule for the counseling rounds, and in that students are arranged in batches according to their SET scores, so you will get an idea, about the your chances for the different streams. 

Symbiosis Pune is a good institution for a B.Tech. Programme, however it is a general trend seen that students prefer to join State Universities over Deemed Universities. Provided you get the branch of your choice, selecting the unversity is completely upon you. 

Please revert if you have any queries, all the best!
