BMW X3 xDrive M40d 326hp

Stage 1 chip tuning for the BMW X3 xDrive M40d 326hp increases power from 326 to 403 hp (+77 hp, +24%) and torque from 680 to 800 Nm. Turbocharged diesel engines offer the greatest chip tuning potential – optimizing boost pressure and injection maps delivers significant gains in both power and torque from low RPM.

The remap is performed on the Bosch MDG1_MD1CP002 ECU (engine code B57D30) via the OBD2 diagnostic port – no ECU removal required. We use Autotuner Autotuner. Results are verified with a dynamometer measurement.

In addition to Stage 1, we offer the following services for the BMW X3 xDrive M40d 326hp: DPF diagnostics and maintenance, AdBlue/SCR system solutions, EGR valve diagnostics, XHP gearbox tuning, BMW coding. All work is performed using professional equipment.

If desired, the BMW X3 xDrive M40d 326hp can be upgraded to Stage 2 – a deeper optimization delivering even greater power and torque gains. Stage 2 involves advanced ECU calibration taking into account exhaust system and intercooler modifications. Contact us for a free consultation to evaluate Stage 2 potential for your specific vehicle.
