Don't know what to tell ya but the dyno doesn't lie. Not sure if anyone else has dyno'd one of these yet, I can't find anyone that has. We've dyno'd 430s on the same dyno and they're around 400whp. Here's the dyno w/ the AFRs, you can see how fat it is up top from the factory, so I'm sure that is affecting the HP.
i guess i was just surprised at how much drivetrain loss their is!!

Blame the DCT for those amazing numbers the 458 puts out with such comparatively little power/torque at the wheels. Look what a DCT has done for that heavy weight GTR.
The 458 is 900+lbs lighter than the GTR and with the Italia having 450whp, plus that trick DCT, I can easily see the performance especially given the power to weight of the Italia.
If the stock GTR can do high to mid 11's @ 120+, due in large part to its DCT, despite its 3900lb weight and 430whp, then the 458 will be even faster with more whp and 900lbs less to move. I see no controversy with the numbers
