I hear the Smarty's do, but it's only up to like 130 or something like that. But no Smarty's for the 6.7's yet. Mine will get up to 101 according to my GPS before it stops climbing...
Got mine up to 105 but let out of it. Didn't feel any kind of speed limiter kick in. Guess I'll have to go out and try it again. This time on a paved road!
