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?

do you have any cax files with any underlying fuel tables, rail tables, or anything that i could use to help get better throttle response, and get the rpms to drop down quicker and not hang in 07.5-09 6.7 cummins trucks. Working on my buddys 08 g56 truck with this OS 55720809. THANK YOU!!!!!
