2018 GTD Golf 7.5 tuning ?

[GTDinGermany]

Hi all,
I'm in the Stuttgart area, but English speaking and have a GTD.

What tune is the easiest to install & uninstall and shouldn't be a problem with the fuel here?
Is there a piggyback or OBD-2 only tune that doesn't require messing around in the engine bay? I can do some of that but prefer not to (also prefer to reduce risk of any damage).

Does anyone recommend any particular tunes, and could any be purchased used reliably and installed myself?

Not sure what are your intentions...Would you like to get more power from engine or what? If yes, visit some company performing chiptuning. You can either get more power with just OEM setup or decide to upgrade some of the engine parts to get even more power from it.

Thanks! Yes just more power and better response.
Air intake for turbo sounds would be fine too
