I seem to be getting mixed messages on this. Is the 2.5 Bar custom OS available for the 2007 Z06? I know there are a bunch running it on their 06 Z now but how about the 07 Z?
If it is available What map sensor are you using? The factory Z06 map only reads to 1 bar. Also is the 2.5 bar a direct fit or does it take a custom harness?
