I have a tune for it. It was done by me so defently not done by a pro but it was running quite well on our TT. Search a bit i think i´ve uploaded the file somewhere. But i would go for the offer from PRJ, in think what you geht there is much better.
Black A4, i used your tune for a long time, its been great. iv since made some "upgrades" to it. i'll upload here
