Who's car 'rarely' enters PE? I thought that was one of the main reasons for changing the factory tune; to get the open loop tables cleaned up to make even power.

I don't see KR unless I am hard on the throttle and not in PE (stock tune). I also would not put much faith in the 'commanded AFR'. There are things going on that do not show up in the commanded value, but show up with a wideband O2.
