Nice Tune (just by looking at it on the computer)..
Does the Lamba follow directly The changes LAMFA? Great idea to change the axis data
If it follows, wouldnt it be better to got a bit leaner?
Did you change MLHFM of this tune step by step for leaning / enriching problematical areas? Or does it differ because of the boschmaf?

Thank you it has been a work in progress for a some time now and I have got it dialed in pretty good. the only bummer is that its super hot in az right now and my stock intercoolers heat soak really fast haha. i just have to save up for new ones.
I just got my AEM wideband o2 sensor and will be installing it today so I will be able to tell you for sure if the requested AFR is folowing LAMFA like it should be. according to my logs I have done in the past it is very close to the 11.8afr. yes it would make a little more power if it was leaner but alot of research by other tuners suggest that 11.8afr is optimal for the S4 and plus i like the safety of more fuel under WOT.
the change of the axis was NVR's doing on his file that I started with so I cant take credit for that
but changing the axis must be done so that LAMFA will work right and not just dump fuel when you are cruising like the stock valve is set up for.
no I copied over the MLHFM values and all of the other MAF values from a stock abox to the Mbox so that the bosch maf can be used.
