can anybody tell wtf my z its only 265.5 cv and 342 Nm ??????

it has only 3000 miles...


Can anyone help

 

What where you expecting. That look about right.

 

it s soposed to have 287 isnt it ???

 

Well, I did the conversion:

269 hp and 252.2 lb ft

I don't see any problem.

 

Looks like you are on a wheel dyno. That 287 HP, not CV, is at the flywheel. I think your numbers are at the wheel, and if they are, then they are higher than the numbers we get over here, but there are so many factors and conversions involved.
