4% diffrence in bank 1 and bank 2? Anything to worry about? My Bank #2 (passenger) reads about 4% leaner than the #1 (drivers). Is this within spec?
Is it just the difference in O2's, or is it a characteristic of the ls1?

Pretty normal, though 4% is maybe at the higher end. Can be due to lots of factors like small leaks in exhaust, worn o2 etc.
You might want to consider an open loop tune if you want them fueled the same all the time irrespective of leaks and o2 sensor condition etc.
