I am having some issues with the programs provided with the Definition file. All the programs make the truck buck and jerk while cruising/ lightly accelerating at slower speeds. They seem to smooth out after the truck completely warms up. If you accelerate moderately there is no issues, otherwise they work well. Ohh and the "stock" file will not do it.

Anyone experience similar issues?

Thanks

P.S. Another symptom might be some dead spots/ delay in the APP, but hard to tell as I was not driving.
