Apparently I have a vacuum leak and mine until its completely heated up and the leak seals off likes to run around 16:1 at cruising speed and idles upwards of 17:1 and it hasn't caused any problems. Before I got the wideband it was running as lean as 19 and 20:1 at light throttle. I've never had any knock counts from it as long as I use a reasonable amount of spark advance. I realize running it that lean isn't good but I didn't know it was actually that bad and it hasn't hurt it any. Once its in tune though I'll try to target 15.5 or 16:1 to maintain some power while at cruise.
