I have HP Tuners and tweaked the OEM tune. It drives like a completely different car with just minor tweaks. I eliminated roughly 80% of the torque management, slightly tweaked timing, and tuned the transmission shifting to my preferences.
OEM throttle mapping is awful, with 50% throttle application only giving around 25% actual throttle. HPT warns not to mess with the throttle tables, as you can brick the pcm if you go past some undefined point of no return. Because of this, I chose to go with a Vitesse throttle enhacer. That's opening another can of worms, as a few people have had issues with throttle enhancers. I have had zero issues, and it's been installed for at least 8 years. I set it up so that the car drives like a cable driven throttle. One of the most enjoyable mods I put on the car because the throttle response is perfectly tailored to my personal preference.

It is worth it if you are in an A6...... The trans adjustments will make your car feel the way it should. HP gain is minimal, but the sluggish feel when you initially hammer it will be no more.
