To be honest, I'm not interested if car has 290 or 310 PS, bhp, etc. Software slowed it down significantly and I don't feel the power anyway. I only put one car on the dyno, because I read this model comes with a bit more power than specified. In the end, it was only 10PS over standard 520PS.
What car made 520ps ? C63 AMG ?
 
I will be honest i know i've only done 500 miles but i thought would feel as fast as my brothers golf R and my mk7 i had but it just does not ,,,,must get to the tuners lol... :p
When I had my Edition it slackened up at 1400miles but then it really came to life after 2000miles, placebo maybe or not it felt a lot more brisker.
