Work on chip tuning Audi a6 was carried out with the removal of the control unit, because at the time of the work, there was no solution for reading and writing the firmware through the connector obd.
The firmware was adjusted to all the wishes of the client, plus was removed speed limiter, which sometimes very interfered.
After these works we got +48 hp and +70Nm.
