as per snow troopers recommendatoins I have changed the cam change over back to stock I also made changes to the readiness code so that it will pass emmissions on the 2000 s4. i looked over the fueling and i do not have the KR fueling activated and thats why it is not configured in KFLAMKRL. If anyone else has any other suggestions by all means let me know.

I tried looking for a stg2 Hitachi tune for 91oct, but I was not able to find any. I particularly like your tune because I have the same exhaust setup with a FMIC and a modded airbox . I bought the car complete stock with a stg1 GIAC tune, but i feel it completely falls on its face with this tune. Being able to tune has been something ive always been interested in excited that i came across this website!

Do you happen to know the threads that have the other stg2 tunes that i can use to practice my flashing? Im sure its probably easy.

Thanks again for the help you are giving me, its really appreciated!

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. 

Ya a 12.5 afr would make a lil more power but ya no egt's so I like the being sure I dont lean out.
Oh ya it's super hot 112F the past few days. Wish it was that nice here. Heatsoak is a bitch haha.

looks like a few of us getting killed by the heat.

Here are some goofy logs running a derivative of this file.  (Tweaked for Bosch MAF and coded out rear O2's)  A couple of times I've dropped into limp mode but I was able to get this pull logged.  I'm running 93 with intake and catback.

I'm still learning how to interpret most all of this stuff but I thought I'd throw this out for comments.  What's the most common cause of actual boost over then undershooting requested boost?

Thanks, all!

How about that WGDC?  I haven't seen enough examples to recognize good from bad. I want to spot and fix any potential hardware issues before starting tweaking things.
