Speedo Calibration
#1
:bang: Hello everyone...have a question. I have changed gears,and i have Predator with r22. Trying to get my speedometer exact. I have gone through tuner and made adjustments...but no matter what i do...i am 5-7 mph off. Speedo reads faster than i am actually going. Any ideas. I have 3.73's with 255/50/17's. Thanks!

It did this on my Dad's '03 Silverado 6.6
We can't figure out why it isn't adjusting the speedo properly...it's ~13mph off and he was pulled over today because of it, so we've got to figure something out soon. (luckily he only got a warning though) We made the tire adjustments, that was it as far as custom adjustments, and it isn't right.

Fidele just asking and trying to help - you changed the gear ratio in the modify tune menu, then saved those changes, then reinstalled the custom tune with the changes - correct?? You should not need to correct for tire size. You have the same size tire as I do and it is within .1 of the diameter as the original tires - that's another reason I chose that size tire.
The current software for the U7140 Predator is r23. However, I don't know what has been improved in the new version so I wouldn't automatically update the tool.
PS: why not 4.10 gears?
