Well, this is essentially an exterior drag view with no data. The GTI has a poor launch but appears to start reeling the Cupra in. The GTX3071 turbocharger should produce more power than the K04 turbocharger so that is exactly what should happen up top. Additionally, there is no interior view or supplemental data.
It is kind of odd to see APR publicly brag like this at the expense of a direct competitor when we all know which setup will make more power and where there is no data at all to go off.
The VW tuning scene is a bit of warzone though, video below.
