I don't know anything about those codes, but I have 3.73s in my car now (A4) and I love them. Not quite as much throttle response as the 4.10s that I had, but def better "seat of the pants" difference than stock gearing. With 3.73s you'll be turning more rpm's on the highway, but with mine I can still cruise at 70mph and am turning around 2500rpm (on a 26.5" tire). Too bad that now my rear is dying and whining like a *****...
