I am considering to buy a 2002 A6 4.2 to replace my S6's. Does anyone have =
or know of someone that has experience in making more horsepower with the 4=
.2 engine? Chip? I only wish for a bit more 350 - 375 would be nice without=
 spending $6000 to do so. My three S6's are for sale as a result.
Thanks,
Tim Leonard
