Problem: Dakota Digital Cruse control works but surges and hunts. DD not any help, last suggestion was have the accelerator reprogrammed. I would have tried that if I could find anyone in South Texas that had a clue what that is. Anyone had this problem and found a cure?

I have it on my L83. I think what they are saying is changing the way the gas pedal reacts. GM has tendency to make their pedals very touchy with the pedal coming on pretty fast. On the stock ECM, you can change how the pedal reacts so it only opens X amount at 10% pedal etc. The guy that tuned my truck adjusted the pedal, but I am not sure what he did. It seems to work a lot better now especially on smooth flat roads.
