Anyone else have a Speedometer reading high
Traveling with a friend that I know has a speedometer pretty good I found I read 64 when he is running 60-61. Local Street your speed signs show me going 3 -4 mph slower than I read. Recently took a trip with GPS in truck and it shows me as going 3 - 4 slower.
Anyone else notice this and or have this?
Can dealer correct it ?

This is common I think. I had an issue with an 02 and the dealer told me law requires within 10% unless its a police/ certified spedo. 10% is a lot to me. What does this meen. More often service, imaginary higher mpg, and warentee running out sooner on millions of vehicles. That being said my speedo read different at different times, worst being telling me my tripometer read 72 while actual was 56. Other guages erratic too.

Mine reads fast, If it says 74 I think I am actually running 72. I like it, keeps the high speed reward certificates to a minimum.
And the nav unit? Yeah, I used to rely on my portable for speed as well. I downloaded an iPhone app that gives me GPS speed but it's not the most reliable. Works well for dialing in the lawnmower and golf cart though!

Any of you guys that have an Iphone or an Android/Droid based phone should check out a program called Torque, There is a free and a paid version. I have the paid one, this program in conjuntion with a bluetooth OBD II reader such as the Kiwi allow you to read the speed from your trucks OBD system.
The reson I point it out is there is a graph in the program that lets you compair GPS speed to OBD speed and I have been playijng with it on mine. It will also read other sensors and such from the truck. I have not tried it with a '11 6.7 yet, as I do not have mine (truck) yet, but it has worked with every other OBD car and truck I have tried it with.

Mine is 2-3 MPH fast.
If you put your info screen into engineering mode and go to the digital speed screen, you'll notice that speed is nearly the same as a GPS device but the gauge is fast.
So the truck knows the correct speed, it just doesn't share that with us and is that way on purpose based on what I've read.

mine is 3 mph fast, the one in my 07 mustang was also 3mph fast. I think what they are doing is using this to make the gas mileage numbers better, while the 3 mph might not translate to the odometer reading it does slow the vehicle a bit and when you start getting to about 75 mph backing off 3 mph will have an effect on fuel mileage.
