RX Reduced Engine Power Chip Tuning

I have an RX as well. Reduced power and stored errors...sounds familiar. Were any aftermarket performance tuning or modifications done to the car's computer?

Chip tuning was performed. Could that be the source of the fault code? Is the car computer overly sensitive?

Indeed. The issue with aftermarket chip tuning, especially from third-party providers, is its potential to introduce instability within the engine management system. It's advisable to consult with a trusted workshop to verify the tuning's integrity and address any resultant fault codes.

Confirmed faulty chip tuning. Workshop visit and correction cost 180€. Thanks.
