Here is the testing procedure for the speedo on an '02 Virage I figure that it would be the same for your '04.
I have noticed that the speedo on mine isn't very consistent. The other day mine read 50mph at 6620 rpms, then 10 minutes later it read 55mph at 6610 rpms.
I would agree with Neal, if you want to get an accurate measure of how mods affect your speed, get a cheep gps unit.
