New to the community with a 2010 S6 and looking for possible ECU and TCU upgrades. I have been reviewing the different posts here but really have not seen much in terms of these upgrades. Any recommendations or is it even worth doing?
I know a few members on here have had it done and seen a brief discussion with APR and JHM… just wondering if there was a noticeable difference.
Let me know your thoughts.
Thanks!
