Hey guys I have a 2011 6.7 cab and chassis a customer of mine owned it befor me and it was tuned when he bought it. Since I have retuned it with Starlite tunes. Question is since I have bought it the cruise has never worked and I have checked all aspects of truck and am leaning towards the tune. 51120807 is the os. Is this right?
