Not sure what you mean by lean mode, but most new ish ecus will adjust(retard) timing if you put crap gas in.

I would assume that if you put 98 in it for a while it'll re-adjust(advance) timing again.

There may be a trick like pulling the efi/ecu fuse and leaving it for 10 mins or so to speed this up.
