With a bespoke remap the Audi A8 4.0 TFSI 420bhp gains +120 bhp and +200 Nm, rising from 420 bhp / 600 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.
Figures are guide values from our rolling road and comparable vehicles. Results depend on the vehicle's condition, hardware and fuel quality. Remapping in the UK: let your insurer know about the modification. DPF, EGR and AdBlue solutions are supplied for off-road and motorsport use only and are not legal for use on UK roads.
