I was planning on taking my 06 MS, MN6, Z51 C6 for the SuperNat 490 hp upgrade next week but now have a dealer who has given me his 2nd 2007 Z06spot due this fall.. so, rather than go with the mods, I was thinking of going the header/pipes, ram air route with my local tuner with my C6.. then when I get the Z, would think about going north of 600hp
Any advice about what you would do?
