Check my sig for VAG log of torque improvement from the BMC CDA I've got.
I don't have a corresponding one for the Supersprint, unfortunately. Chip companies usually claim about 10-15lb.ft. gains, and I've heard of no high flow cat specifically for our cars.

From what I can feel, the exhaust mostly helped with throttle response, not as much on power...
If I'm to venture a guess, the Supersprint, which I did first, gave me at most a handful of horses, and then the CDA gave me the 10-15 you saw on my plot (which I cannot say if is at all amplified by the freer exhaust). The Wetterauer chip I've got sitting on my desk for a long time now is advertised for another 10 or so. I'm not aware that Miltek has a cat specifically for the 3.0; do you have any link? My guess is that's gonna give again at most a handful of horses, if not neglible... One thing you didn't mention are headers: Supersprint has a design for the 2.8 that they say would also work with our 3.0; that's claimed to be good for 5-10hp. The big thing about headers however is that the engine needs to come out for the install, so they'd be rather expensive in the end.

You're right...no Miltek cat for the 3.0 on Stratmosphere site, but I found this...
apparently for the 2.8 on the B5, which I found intriguing. Can't vouch for them, no experience w/ them. I don't know if they'd work in a B6 application.<ul><li><a href="http://members.aol.com/SportsCarConvert/AudiAS.html">http://members.aol.com/SportsCarConvert/AudiAS.html</a</li></ul>
