Hello everyone, I am will be getting a newer Audi A4. I currently have a 2002 A4 Quattro. Im looking into getting either a 2006 A4 or 2009 A4. I will eventually be doing some engine mods to make it faster. I know the 2009 A4 has 11 more HP than the 2006. Is one easier to tune than the other? Could I get more HP off of the 2009 model?
