Yup, 5-10 off definitely sounds like you just
might be running 35s.
To correct that go to the gryphon and go into the custom options menu next time you reprogram and check your tire size. It is probably somewhere around 2300-2400 mm. If it is try a number around 2800. If you have a GPS go by odometer readings for the most accuracy. (Truck odometer divided by GPS odometer then that multiplied by the current tire size) Dont forget to load the previous settings, even if you havent made any changes. It's a good habit to start.
