Has anyone installed a shift kit in their A4 GTO?

Good results?
I'm looking to do so, who makes a good product?

I think the popular thing to do for A4 owners is to get a full tune (dyno or programmer-based) rather than go with a kit. The results seem to be more positive.

Not sure about the shift kit but getting a Torque Converter and ECU hand held programmer (DiabloSport Predator Tuner) would also help.
