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). 421 → 470 bhp equals roughly 314 → 350 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.
