With a bespoke remap the Mercedes Benz S 500 (3.0T) 435bhp gains +45 bhp and +80 Nm, rising from 435 bhp / 520 Nm to 480 bhp / 600 Nm (10% more power). We build each tuning file around the software number of your read, so nothing generic goes back into the car. Add DPF / EGR solutions 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). 435 → 480 bhp equals roughly 324 → 358 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.
