Retrofit/modification to my car

Hi everyone,
I'm looking for a reliable and professional tuning/retrofit shop in Łódź, but I don’t mind driving to Warsaw or nearby areas.
I want to upgrade some parts of my Audi A4 (automatic/S-Tronic). It currently has a comfort-level trim, and I want to switch to the Virtual Cockpit screen and install a new steering wheel, including all the necessary software updates, component protection removal, and coding so everything works seamlessly like a factory setup.
Does anyone have personal experience with a shop that specializes in VAG (Audi/VW) retrofits, coding, and parts sourcing?
Thanks in advance for any recommendations!
