It's probably been on a honest dyno. So many it seems mostly Americans just go do a road tune and go uh yea it's like 700-750hp when in reality it's probably 400 etc
That’s more than 610 I swear! My mk4 r32 f.i is running over 700 and don’t seem anywhere near as brutal. Except right at the end of the video, looks tame 🤷♂️
