Hello!
I bought an Audi A6 (C4) 2.5 TDI quattro, manufactured in 1997, with 103 kW of power last week.
I would now like to have my car's performance improved, but with so many options available, it's hard to know where to start!
Since my 'old' TDI (Audi 100 Type 44 with a 1T engine) has always remained completely original, I haven't had any experience with chip tuning.
Has anyone ever had an A6 tuned, and if so, where and how satisfied were you with the results?
Best regards, Sandro.
