Others here think my range is too lean as well and say it needs to be .82 which to me is on the rich side still.

Since it is Direct Injection I guess it can run a little leaner than what the older engines could get away with. But I'm not sure if I'd be completely comfortable with it running that lean tho. I say that but meanwhile I don't even know where mine is at. LOL!! I'll see what I can find out for you so we can compare notes.
.88-.89 does seem to be pushing it closer than what most do. It sounds more like an aggressive tune.
