No new power figure is published for an economy file. It is written for torque and drivability, not peak output.

What ECO involves

This one is aimed at running costs and how the car drives day to day. Torque comes in earlier and more evenly, so it pulls without needing revs. Driven sensibly it will usually give back a little on fuel. If you are after outright power, look at the other files above.

It takes most of a day. We keep your original file, so it can go back to standard at any point. Figures here are for a healthy 4.0 V8 TDI, and we check the car over before writing to it.

See the full 4.0 V8 TDI page for every file and figure, the other engines on this A8, or all Audi remapping.
