What I would do is find someone with a copy of Cummins Insite and have them plug in and see what the programming is as far as maximum speed without a VSS signal. If it's 30 MPH, I think that's your answer right there. I would also monitor the vehicle speed signal with the laptop while you're going down the road and see if the signal closely follows what you are actually doing.
