Unsure if its just my truck or all of em, but... The cruise is really abrupt. It seems as though it completly defuels when it gets above the desired speed. Its really hard to live with massive jolt everytime. is it my truck?

 

If I let mine accelerate on its own to a preset speed, I've noticed it accelerates slowly(compared to my lead foot LOL). Once it gets to that speed, it does sort of let off, but nothing I'd describe as a jerk or a jolt.
