It's a slippery slope.

Here are the perf mods that I've done to the powertrain since owning my car:

1) buy new 95.5 S6 Avant in December 1995
2) chip and add RS2 (IA version) manifold in 1996 (~$1500)
3) replace head due to dealer screwup in 2003 (> $8K but free to me)
4) add RS2 MAF, FPR, injectors, silicone hoses, metal ('93) capped stock IC,
   Stromung exhaust, 2B K26/27 turbo, Forge BPV, 7A cam, 3 BAR sensor and 
rechip

The exhaust manifold helped lower the engine temp even before I added the 
larger
turbo. Step 4 above was done over a couple of days. At one point, I had the 
new
firmware and 3 BAR sensor in with the old turbo. I had to watch that I 
didn't
overspin the turbo. That baby really wanted to sing and noticed much, much 
better
low end response than stock or previous chip level.

Are you putting $1-2K only in this, or is that all you can spend today? If 
the
former, maybe an exhaust and a manifold (closer to $2K). That shouldn't 
require
a rechip, which will take a large bite out of this sum.
