The BMW 520i came in for chip tuning and catalytic converter removal.
Our specialists first checked all the car’s components for correct operation and absence of deviations from the norm.
Next, the catalytic converter was removed and replaced with a flame arrester.
The firmware was read through OBD and sent to an engineer for adjustment. After receiving the ready-made software, it was uploaded to the ECU and the car was placed on a stand to check the logs and power.
As a result, chip tuning and catalytic converter removal added +86 hp and +160 Nm.
