EPL's fix fo the 'cat protection loop'?

Not sure to what Tony is referring to here: http://www.audizine.com/forum/showthread.php/642964-EPL-B8-Product-Updates-and-Development!?p=11511971&viewfull=1#post11511971

From the thread:

[quote]That said, I’d be FAR more worried about the factories poorly tuned “cat protection loop” burning things up, then any additional fuel during heavy load.

Any ideas?

Since most people dont listen to EPL they have been doing this for years. Comming up with little things that are not things to make it sound like they are doing something you need to have done.

The issue that I can see running the car lean in certain area’s would be increased EGT’s, which will still age the cat. Audi tuned it to run rich in certain conditions for emissions reason I’m sure…
