Exactly I just wasn't sure what the actual numbers were so I just threw a couple out as an example. Thanks for the info though!

No one ever got fired or sued for underating numbers. But Ford got sued for over rating the Cobras if you'll remeber. GM wants to ensure tha tthe worst motor will make 505. Those that come out slighly ahead, are just icing on the cake for the owners.
Also you'll find the loss in the driveline to not be a percentage, but rather a fixed loss. On a C5 its about 50-55HP going from a Superflow to a Dynojet. On the C6Z06 I don't know as there is more mass in the rearend.

I definately agree about the IAT mapping for these cars. You can feel the power loss on the street as well its so noticable. We are still waiting for EFI Live to release there LS2/LS7 package as we are invested into there software. We are going right to that table as well as the PE Modifier as this baby is silly rich at WOT. Those numbers where at a AFR of 11.5:1 across the whole pull.
A couple degrees of timing shouldn't hurt either!

Looks like alot of good info. is coming out and will undoubtedly continue to do so. Once you tuner guys get finished with even a stock LS7 I'm sure you'll turn out some even more awesome #s.
