I traded my 2010 rt challenger for an 06 a3 3.2 Quattro.Ihave diablosport trinity for the challenger to increase horsepower and fuel mileage.im looking for something similar for the a3.Anybody know a programmer that can achieve this?One thing about the trinity was that you had to stop and park to switch from mileage booster tune to performance and vice-versa,I wonder if theres a device that allows you to adjust settings on-the-fly or different tunes while the car is driving.This is my very first post to this forum and I'm a new audi owner so sorry if I sound like newb.

 

No such device exists?
