Why doesn't Audi offer what aftermarket chips do?
I keep reading about the wonderful things that engine and tip chips do. Presumably Audi knows as much as the aftermarket chip makers do about how to make the engine and transmission work best. So why does Audi not make the stock chips work as well as possible or, alternatively, offer their own enhanced performance 'sport' chips as an option?
What are the considerations that argue against what aftermarket chips do to the engine and transmission controls? Are there durability issues? Emissions? Tractability? Safety?
If Audi can make a 'sport mode' as part of the stock tip, could they offer a 'sport' ECU as an option? If not, why not?

Re: Why doesn't Audi offer what aftermarket chips do?
Do not kid yourself. Those little turbos were not designed for higher pressures. Chipping will decrease their reliability. I do not believe Audi engineers are so stupid to give too much room for aftermarket improvements. If you want performance you have to cough up a lot more $$ for something like RS4 or RS6. In those babys the whole engine was reworked by aftermarket company quattro GmbH. For example RS4 engine got bigger turbos, different cylinder heads by Cosworth, better cooling, etc. I've read that extream heat production was a big stumbling block in making RS6. Be happy with the fact that we are lucky to have biturbo engines in allroads. A6 avants are not as lucky.
Re tip chips I do not know. I've read stock 2002 tip controllers are better than 2001. Maybe this is the way to go?

Re: Sport mode?
You're correct; it's a 2002 thing. This year, in the U.S. model, the Tip shift designations are PRNDS, with "S" being the same as "D" except for more aggressive (Sport) shift points. Mostly, the tranny will shift at higher RPMs.
