Who is this remap for?
Naturally aspirated petrol engines gain less than turbo engines, but a remap still improves throttle response and smooths out flat spots in the power delivery. 231 → 270 bhp equals roughly 172 → 201 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.
