1. Peak Power at 4600rpm. It's not a Diesel. The worst Cossie graphs are usually from cars with standard cams, the power peaks at around 5000rpm, then goes flat. Yours is on such an EPIC downward. Power curves just don't do that. Well, unless you're running a restrictor on your turbo.

2. The Torque is, as most people have agreed, WAY too high. This is again indicative of wheelspin, or some kind of slip (which would be why the power has done what it has)

3. Roller speed was used. WHY WHY WHY. Why not measure RPM properly, if you're so interested in following DD guidelines to the letter, GET THE FUCKING RPM ADAPTOR OUT THAT YOU BOUGHT AND CLIP IT ONTO AN HT LEAD!!! It's not rocket science. Then you could PROVE that the car gripped, by posting RPM vs Road Speed.

Why don't you guys humour me, on the next big power Cossie, run it your way, then run it my way. See how they compare. I'm only saying it because we had all the ideas about following the manual when we first got our DD, but experience has taught us better.

Take it or leave it, that graph is wank and I'm SURE the car isn't that bad. I feel sorry for you ASHCOSSIE, you got a very inaccurate result there.
