I remember a while back reading about how the Predator didn't correct the speedo right. Well, mine has been off forever. I got a GPS with a map program for my laptop and it has you speed on it as well. Well, at 90 on the speedo, I'm going 79 on the GPS, and at 45 on the speedo I'm doing 40 on the GPS. So as speed increased, so does the error of the speedo.

Stock: 342 rear and 235/70 16 tires (29.9" tall)

Now: (well for the last 3 years anyway) 373 rear and 285/50/18 (28.5" tall)

Yes, all this has been input into the Predator, but it is still off. Anyone have or even remember what the corrections were? I guess I could experiment, but I'm lazy! LOL!!!
