  • Worth the wait...

    I've recently updated the ECU in my 2016 S3 to stage 1. I've had the car since new and I'm so happy I've finally pulled the trigger. Power has significantly improved. In dynamic mode, the car pulls readily in every gear. Under normal driving, performance remains as before, and daily drive-a-bility has not been affected. I am very happy with the results and I wish I had done this sooner.
    Thank you Modded Euros for the prompt shipping and to Unitronic for its customer service. Looking forward to Stage 2!
