This 2007 BMW 335i E93 with a twin-turbo petrol engine and MSD81 ECU was tested on 98 RON petrol. Its exhaust pipe configuration had been changed, while the catalytic converters and oxygen sensors remained fitted. The initial dyno run produced 319 hp and 457 Nm.

Calibration results

After calibration, the dyno showed up to 385 hp and 596 Nm with traction control switched off. A run with traction control enabled produced about 370 hp and 585 Nm. The dyno result therefore also depended on the vehicle’s control-system settings during the test.

These figures were recorded on this specific car with its exhaust configuration and 98 RON petrol. They should not be treated as results for a completely standard BMW 335i.
