I have a 99' A6 2.7t with Tiptronic and Bosch MAF. I would like to replace my original file with a more common one, but I'm not sure which one to use.
Is it only possible to flash Bosch MAF files or is it possible toto recode a Hitachi file to Bosch MAF?

What would you recommend me to do?

I just found the info  at S4Wiki, that it is not possible to code engine with:
Bosch Maf
ESP
Tiptronic
I guess there was no S4 with this combination or is there any?
It doesn't matter for me if the file is 29f400 (512kb) or 29f800 (1024kb) as I have a socket on my ECU and can use both cip types...

I have a nice stage 1 tune that I like a lot good mpg with new dv. It's not mine but someone else's but yes it's Bosch. Also have a s4 stock 265hp LBox Bosch too. All for tip and I have tested them can upload if you want in the morning. It's about a 40hp or more increase you get to feel the boost now. It's a 91 octane file.
