Glad to see it's finally here. I just wish the GXP was available now. I've have a 2006 GTO and will be glad to have a G8 GXP sitting next to her in the garage. I just don't understand why the LS3 will be 'detuned' down from the 430hp that is's capable of in the corvette. They didn't mess with the LS2 before the dropped it in the 2005 GTOs.
Is it confirmed that the LS3 willl only be rated at 402hp in the G8, or are they just underating the numbers? Anyone know for sure?
