No idea about the box but if its like the one they use its gotta be pretty good.
The vids Romain ?? has posted there own car looks ACE.I struggle to understand why they have not responded because the guy seems ok on here .
I think if its something they use and are selling its gotta work otherwise why would you put your reputation of 800bhp cars at jeopardy.Slow response time though
Pm him and see if you get a reply
