870 demandate question

[Redland1]

I ran across an old Waterloo post where he was saying that on the 870 you have to remove the center plug pin for the Delta P sensor even though the truck is demandated because it can put it into a silent derate.Just did the pin removal yesterday.Is there anything else that needs to be done on a CM870 once demandated? Besides removing the cooler if one wants to which I did and putting in a block plate where the EGR went.

Asking because my truck hasn’t been running the best and has poor fuel mileage as well.
