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. 420 → 440 bhp equals roughly 313 → 328 kW.

Figures are guide values from our rolling road and comparable vehicles. Results depend on the vehicle's condition, hardware and fuel quality.
