We have already a tuning for your Audi A6 available. With this version power will increase to 185hp and 390nm. We have tuned this 2.0 TDI engine many times now so we have already gained very good experience in tuning this engine. The customers have all been very satisfied with the results.
Please do not hesitate to contact us if any other questions may come up!
At the 150hp models we usually reach an average of 190-195hp with our upgrade. We already had one which showed 202hp after the upgrade, but it's always a little bit car/engine depending (that's why we usually give values in our database which every car will reach)
