Ram cp4 failure thread - Post all CP4 failures here DO NOT start a new thread.
My apologies, edited post to remove name. From what my dealer was saying reflashing a CP4 tune on them was causing alot of fuel pressure irregularities causing the truck to not run right. Im wondering if maybe there was a tune out there for the updated 6.7 with the CP3 on it.- Alexcollins

Hey there, new to this site but im running a 2020 ram 2500 deleted and tuned with a 45 over tune. Been back and forth with my dealership about getting the CP4 (Y78) recall done. So far they only did one truck thats been deleted and theyre still having tuning issues with it. Figured is post here...- Alexcollins
