Probably not a *whole* lot without also an ECU software mod.  But then
I am just guessing.  Most people who do mods on 2.7Ts start with
the ECU first and then go from there, because that gives you the
most power increase for the money.  As you noted correctly, the K03s
do have their limits and "chipping" takes away the safety reserves
built in from the factory.  However, the various vendors' chips vary
in how hard they push things and if you're not abusing the car (and observe
proper warm-up and cool-down procedures), then chances are chipping alone
could be perfectly good way to go if you're not looking to spend a lot
of money.

I don't know how many people on the "ba-group" list have 2.7T cars,
but you might try subscribing to the "biturbos4" list also hosted on
audifans.com.  There are some A6 2.7T people lurking on there, and
of course the S4 biturbo has the same engine too.
