Who is this remap for?
On a diesel, the bigger gain is usually in torque. Expect stronger pulling from low revs, easier overtaking and a more relaxed drive on the motorway. 496 → 600 bhp equals roughly 370 → 447 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.
