Actually I took it to the dealer. And I was informed that Chevrolet will not release info on the l5p Duramax to reprogram computers. If you know a dealership that will do that on a l5p in Southern California please let me know. Because I will go to them.

Hello, I have a 2019 3500 l5p. I did a gear change from 373 to 410. Now my cruise control will not work over 51mph . I bought the Edge pulsar programmer , and that fix the speedometer calibration but not the cruise control issue. So has anyone else had this issue and what is the fix for it. Thank you
