I have an 08 6.4 with dpf and egr delete, running the H&S mini maxx. Right after I did my EGR delete (around a year ago) I had to cut out my up pipe that went to the EGR cooler because of a leak. I relocated the block off plate and EBP sensor up by the turbos at that joint. Ever sinse then I go threw an EBP sensor about every 3 months. I monitor the number with my mini maxx. It will be reading normal and just drop to zero all of a sudden. Replace the sensor and it is good for another 3 months. I still have the stock tube on the sensor as well. Anyone have any issues like this before and does anybody know why this happens or what causes this?
