Anyone have a fix yet? Hate that it's off by 4+ after 70mph. SCT x4 with PIP Tunes.
I'll look into hypertech for sure.
Nah options are just some lower number to 34". I have 3.55s
You could change your gear ratio to 3.31's in the tuner with 34" tires. That should get you a little closer if you haven't tried that yet. I had to do that before with a different truck.

I did not, However I do nowYou do realize the speed sensor counts the rotations of the carrier? Doesn't matter what gear ratio you put in it, it's still going to count how fast it actually rotates. It's not like the old cars where the speed is measured in the transmission.
