I would say them claiming 820hp is a bit of a stretch. You are probably putting down 640whp (which is great) but that doesn't equate to 820bhp. I think the whole 820 is a bit of a marketing ploy. I am sure your car is night and day from what it was so that is awesome!

Yes I remember it was 62-65whp. Even my GTR gained 55whp with my catless down pipes. I can find those pics of the dyno results somewhere on some tablet in my house. I will try to find them.
Marketing ploy? Possibly. I'll know more once I get this big bitch on that dyno. But I finally had a chance tonight to play around with my buddy's F10 M5 with no down pipes, some muffler delete, and some random tune. Even with the split second jump he got on me, I was able to pull roughly 4 cars through just 3rd and 4th. And the entire 3rd gear, the rear of my car was fidgety. I am installing a pair of 305-30-20 Michelin Sport Cup 2 tomorrow (rears).
