With a bespoke remap the BMW Z4 3.5is - N54 - 340bhp gains +30 bhp and +50 Nm, rising from 340 bhp / 450 Nm to 370 bhp / 500 Nm (9% more power).

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. 340 → 370 bhp equals roughly 254 → 276 kW.
