Congratulations on the RS6. mmmmmm I am also a convert from BMW to Audi (check sig). I love the BMW's I have, and will probably never get rid of them (except for the X5), but the new designs and "Why-Drive" kept me away from anything BMW is producing right now. The only thing that kept me away from the RS6 was the Auto-tranny. It's still one of the best auto's I've ever driven. My friend lets me drive his quite a lot and has basically the same mods you do, except he has O.C.T. instead of GIAC. That car has got some stupid power and on the highway will take the Z8 pretty bad. Congrats! :1:
