My JC'ed e30 trained me to use high octane, so when I got my ti, I automatically started putting 91 in it, with stock software. The few times I've topped off with 87, it seems like I get slightly worse gas mileage, and I think I can feel the knock sensors retarding timing on real hot days.

That said, I think the use of highest octane possible is VERY sound advice when you're running a chip...I know of a few people that can't even run 91 without throwing CELs w/JC chip.
