The BMW E60 3.0d had previously received ECU calibration work and a hybrid turbocharger cartridge at AutoChip. A larger intercooler was fitted later. The turbo housing remained standard size, and the sensors and injectors were not changed.

After the intercooler was installed, the car was checked with its existing ECU calibration. The dynamometer recorded 331 hp and 752 Nm. This reading represents the larger intercooler working with the previous software.

A more powerful calibration was then installed, along with launch control. Higher figures are also mentioned at the end of the video, but it is not clear whether they came from a separate dyno run after the new software was fitted.
