That's the only info I could find on the internet also thanks though.

It only throws the code on the GH tunes I just got switch back to my old tunes it won't throw the code.

Battery voltage is good (14.1-14.2 volts)

PCM connectors are good/tight and don't have any corrosion.

very strange. I've never had a problem with his tunes on my 6.4's

maybe the tire size value got messed up?

I set to 550 with the tuner and I checked with AE and it set to 550.

I also have a high idle problem I don't know if that code is related but when the truck is at normal operating temp and driving if I go over 1/2 throttle it will high idle (850) and if I let the truck sit and cool down for 5 mins it will idle at the normal rpm (650) and go back up if I go over 1/2 throttle again.
