I am not sure if it's a bad thing, necessarily- the IAM is very eager to move around right after a reset and then it should ultimately become more stable after more driving. I would give it a day or two and see where it ends up.
The KC numbers are dependent on the tune- just because they aren't at 10, doesn't mean there is a problem. I would look at the overall ignition timing curve to see how it looks. If your car is pulling timing for some reason, the retarded ignition might be the cuase of your high egts. What kind of temps are you seeing?
