Remapping the BMW 520d
A Stage 1 remap recalibrates the factory ECU software to improve throttle response and smooth out power delivery, within limits appropriate for a standard, unmodified BMW 520d.
As a turbo diesel, this platform is also commonly approached for economy-focused tuning, which can improve drivability and reduce gear changes on longer journeys. We don't publish generic bhp or torque figures, since actual results depend on the specific vehicle's condition, mileage, and history, confirmed properly during a suitability check.
