Bought a 2019 2500 about a year ago and the DPF got clogged up about 6 months ago. Was told $10K repair with dealer or delete the DPF and add a tune for $4K. Not fully understanding what I was doing I went with the cheaper option. Now we have the recall for the CP4 to CP3 fuel pump conversion. The tune is stored in the PCM and will get wiped when they reprogram it for the CP3. There is no replacement tune for the CP3 at this time. Has anyone run into this issue? Any suggestions? I'm new to this forum so please direct me if there is already a thread on this topic.
