Nice sound !
I have a Audi s3 8V FL 2017 I want To decat it however does a decat need a mapping I.e stage 1 ? As I’m not looking for Mapping , I know it will need a tune for the EML to come off the dashboard.
Thanks

Id be tempted to go for a high flow race cat instead as not to be an issue at mot time. But either will need a remap.
