This single-turbo BMW E92 3.0D had already been programmed at two other workshops. It has a larger turbocharger compressor assembly and a modified exhaust system. AutoChip tested the existing software on a dyno, recording 218 hp and 611 Nm, then prepared a revised ECU calibration.

After the software changes, dyno readings were approximately 313–314 hp and 675–679 Nm. Data logs were used to assess turbocharger and fuel-system operation. Further power increases were not recommended given the installed intercooler and fuel-delivery capability.

Blue-white exhaust smoke was visible during the test, particularly at idle. The presenter attributed it to the missing catalytic converter, but no separate repair or verification of that cause was shown. The dyno result should therefore be considered alongside the car’s modified configuration and the observed exhaust smoke.
