2003 A4 1.8T FWD Tuning



I was wondering if there were any companies that offer the option of a "piggyback" ECU that would allow changing of programs with a laptop? I used to have an EVO VIII and there were a multitude of companies that offered this (i.e. Vishnu Tuning) for that car.

It just seems more cost effective than having a spare stock ECU for installation upon Audi scheduled service. Just trying to enjoy the benefits of ECU tuning without having to reflash my existing ECU while also purchasing an additional stock ECU.

Any comments would be appreciated! Thanks!
