Audi A6 S6 4.0 TFSI 420bhp tuning file

With a bespoke remap the Audi A6 S6 4.0 TFSI 420bhp gains +120 bhp and +250 Nm, rising from 420 bhp / 550 Nm to 540 bhp / 800 Nm (29% more power). We build each tuning file around the software number of your read on the Bosch MED17.1.1, so nothing generic goes back into the car. Add DECAT, DTC Removal, FLAPS, Pop & Bang Crackle map to the same file if needed.

Who is this remap for?

On a turbo petrol, a remap sharpens throttle response and pulls harder through the mid-range. For the best result we recommend running it on super unleaded (97–99 RON). 420 → 540 bhp equals roughly 313 → 403 kW.
