RE: Engine code recurring, please help!
Totally understand, Im thinking of taking the TTDA box to the next level, and instead of using a bunch of insulation, make it double walled, and draw a vacuum between the 2 layers. I only buy what I def. can't build.
About the cats, most these days (from what I've heard), are fairly free flowing to start with. The setup on the TT is actually 2 cats, side by side. You probably could get a hp improvement from removing them, but I wouldn't expect a 'plant you in your seat' gain. If you can get around emissions, and the car will run well, I wouldn't stop you, but for those who DO have to deal with emissions, time is probably better spent on other improvements.

I'm actually more interested in the car running smoother, hearing more of that muffled growl and turbo whine, and the crispy throttle response that comes with straightpipes.
I'll let you guys know!

OK, not to revive an aging thread here, but the error is definitely because of a chip, right? Also, the only way to find out what kind of chip is hope that the installer of it left a sticker in there? Is there someone I could take it to who could tell me without charging me?

The error may or may not be in the chip. As was said, slow down and give it time. Also it would help if you would get VAG-COM and see what the codes are. You may be having a recurrent code, but without knowing which one you are throwing it is hard to diagnose.

A standard OBD-II won't work? I don't have the code because the d@mn mechanic cleared it before I could write it down. I can get it back, though.
The car runs ultra-smooth, and it doesn't feel like there are any errors characteristic of a bad fuel map or malfunctioning electronics.

Well..... with VAG-COM you have the ability to log blocks when the car is running. It's really helpful to diagnose a lot of problems. For instance a good set of diagnostic logs to run are:
002: Mass air G/sec
118: Intake temp/N75 Duty Cycle/IC pressure
204: Command, IC, and Manifold pressures
3rd gear run WOT 2K to redline.
You can't do that with an OBDII reader.
