OK, so you'll want to see between 0.90-1.00, but ideally closer to 1.00 on cruise (off-boost) and somewhere between 0.76-0.82 on full boost.

If you're driving it to have it set-up, I'd be concerned if it's richer than 0.70 anywhere or leaner than 0.90 when there is any boost involved. Obviously you'll not need to be driving it that hard anyway.
