I installed the TB bypass kit when I tossed on my new TB. You aren't going to feel anything, unless you can amazingly feel a 2HP increase
Takes just a minute to install, not really worth it IMHO but I got it with the Stage 2B.
H2 Daddy - The new vettes look the same basically, except for the Z16. You should just heavily modify you're C5! When you say heavily...do you mean supercharger....or TT possibly? I'm going to TT my Z later this year I'm hoping.
