About the remap

Stage 1 chip tuning for the BMW 5 serie 550i 407hp increases power from 407 to 471 hp (+64 hp, +16%) and torque from 600 to 700 Nm. Turbocharged petrol engines respond exceptionally well to ECU optimization – adjusting ignition timing, boost pressure, and fueling maps unlocks the hidden potential built in by the manufacturer.

The remap is performed on the Siemens MSD85 ECU (engine code N63B44O0) via the OBD2 diagnostic port – no ECU removal required. We use Alientech KESSv2, Autotuner Autotuner, ByteShooter Toolbox and other professional tools. Results are verified with a dynamometer measurement.

In addition to Stage 1, we offer the following services for the BMW 5 serie 550i 407hp: XHP gearbox tuning. All work is performed using professional equipment (ZF 8HP70 gearbox).

Every vehicle undergoes full diagnostics before and after the remap. We keep a backup of the original ECU calibration and guarantee the option to revert to stock settings at any time. JVK PRO is a professional chip tuning service in Riga with 16 years of experience.
