When I look at a log, I always like to view the original .csv file, and the first thing I look at is individual cylinder timing correction. Which cylinders are "noisy" varies from car to car, so viewing all them at the same time gives you a good idea of overall timing correction. Correction in 1, 2, or sometimes even 3 cylinders under load would be somewhat normal. But, consistent timing correction in 3+ cylinders under load typically means the tune is too aggressive for the car.
