'06 Z06, '05 CTS-V 453rwhp/434rwtq (sold)
About 330-335rwhp on a dyno jet is a fairly good estimate.
the black has a tendency to fade to gray and the leather looks worse when it gets worn, that's my only problem with it.personally, i hate the all black interior. its like a cavern. i LOVE the cashmere interior in my CTS though.
