Knock/Detonation...prolonged use of 87 when your tuned for 91 could cause engine damage eventually.
Best put back to stock if your running regular. I know when I had my diablo and ran 87 when I was tuned for 91 I could hear pinging (could have been in my head) but I just removed the chip until I could fill up with 91 or 94 again.
