Has anyone fitted one of these https://www.racechip.co.uk/throttle-tuning/xlr.html

and got pictures how to do it

Several Superb owners have fitted them, they really are easy and can be done in less than 10 mins, all you need to do is remove the plug that goes to the throttle pedal, plug that into the box, then plug the box into the pedal, then store the box safely somewhere (the cubbyhole is ideal) 

As Gizmo says, real easy.

Different make, but same fitment procedure:
