Your AFR is in line with what i would expect to see at that high RPM, during a short 2 second low gear WOT pull. Not enough time for the DME to hit the AFR target. Try again in a more appropriate gear and start the run at a lower engine speed and you will probably see something different.

And please, let's keep on topic.
