Service details
If your vehicle is a BMW X5 3.5i N55 E70 with an original output of 306 hp, this entry provides a starting point for discussing chip tuning. It lists a petrol engine; compatibility with the actual ECU is checked separately.
The configuration name explicitly identifies N55. Keep that distinction when ordering: a version with a different engine designation should not be selected solely because the badge and power output match.
Figures for this configuration
- Power: 306 → 360 hp (+54 hp).
- Torque: 450 → 570 Nm (+120 Nm).
- 0–100 km/h acceleration: 6.8 → 6.1 s (−0.7 s).
- Listed maximum speed: 235 → 265 km/h (+30 km/h).
For the factory 306 hp / 450 Nm version, the listed increases correspond to approximately 17.6% more power and 26.7% more torque. These percentages are calculated from this entry and help compare different catalogue configurations.
The comparison applies to this catalogue entry. Confirm the original vehicle specification before ordering; the listed results do not guarantee identical figures on every vehicle.
Choosing additional options
This configuration uses a Stage 1 / Stage 2 form with additional tasks: VMax speed limiter adjustment, rev limiter adjustment, Popcorn, selected DTC deactivation, catalyst deactivation, EVAP / DMTL deactivation.
Select only the tasks you need. Compatibility of each option and the requirements for the chosen Stage are checked against the vehicle and ECU before work begins.
For the E70 generation, the software read/write method is agreed after ECU identification. The model badge alone does not identify the required interface or connection procedure.
Before ordering for BMW X5 3.5i N55 E70, prepare the VIN, current software details and your preferred options. Identification is needed to agree on the appropriate configuration, working method and price.
