Very interesting seeing these dynos. The shape of the curve of the Z4M is so different compared to the E46 M3, at least based off all your stock and tuned runs.
Would any of you mind emailing me your DRF files for me to take a closer look before I make any conclusions?
In regards to AFR targets. I have seen a wide variety, but if I recall, they try to target mid 12s to low 13s.
