Could you guys take a look at my datalogs?

I'm a new Cobb user. 2010 335i xdrive AT. DCI, just changed sparked plugs last night for first time (26,600 miles), Stage 1 Aggressive ST v. 4.01, Shell 93 gas.

I did 4 pulls in 3rd gear last night. Datalog 8 goes to redline. The others are WOT up to about 5k RPM. Changing the plugs seem to have eliminated most of my timing corrections across multiple cylinders that I was having. I'm most concerned about my AFR. Am I running too lean on turbo spool up at the beginning of WOT or is this normal for my car and modifications? Does the car look happy or is there anything glaring that I should be concerned about? Thanks!
