The products installed at Scottsdale Audi are as follows;

(1) 1.0 Bar APR chip
(2) Short shifter (unknown maker)

The car is dynamic without any of these items. But, with the addition of these items my car is crazy. If you are looking for a car that loses no races ,then this is the car to get. Zero to 60 is second to none. The car does not feel fast. But as you see the car racing you disappear in your rearview mirror you understand its true furry. With the good there is bad. It is hard on the twin turbos. BUT with the 4 year 50,000 warranty who cares (lol). I already took out my turbos within the first 10000 miles. It took AUDI 2 days to put new ones in and have my car back to me (IMPRESSIVE). I was given an Acura as a loaner (free gas, unlimited miles, Etc.).

Also, Garrett makes a much stronger chip then APR. But beware it is twice as hard on the
turbos. And it makes the drivability of the car a LOT less luxurious. It is for the track ONLY.

Other than what I wrote. The car is a dream. I am glad I passed up BMW, Benz, Jaguar and Lexus. These cars are all good. Still they are nothing compared to my S4. Bring it on new M3 owners. I love to beat you.
