in any event, i only know of one vehicle speed sensor on your car

if i had to guess, (this is a guess), it'* intentional if it'* not quite lining up. i've heard on many trucks, the speedo is always clocked fast to help truckers stay within the limits of the law unwillingly.
anyhew, it could also be the refresh time of the HUD. i drove a park ave ultra and a GTP just about side by side, and the HUD refresh on the ave was much slower - it took a rolling average over almost two seconds, while the GTP refreshed more frequently.

They're driven buy the same sensor in the trans case right abouve the differential. I wonder if swapping sensors would make any difference?
