✅ **Yes — several owners have seen performance improve after an ECU reset o r update.

Issues reported:

Throttle lag

Jerky gear transitions for AMT variants

Poor idle compensation

🧠 Dealership action: Request an ECU scan and software update if the problem is persistent but no mechanical issue is found.
