Im getting ready for my EGR and oil cooler change and was wondering about the up-pipe modification. I am installing a BPD EGR cooler upgrade (lifetime warranty) but keep reading about the up-pipe scoop modification. Is there really a benifit to it? If I just remove the scoop and leave it open but not blocked I will still get gas to the EGR so no codes, and that should reduce the restriction thru the pipe right? Let me know if my thinking is wrong. I dont really want to run tunes to get rid of a CEL, but reducing the total amount of gasses flowing thru the EGR plus reducing pipe restriction seems like a win?
Thanks

 

That's a good question. There is an EGR code for low flow, but I'm not sure what sets it. I know the 03/04 trucks didn't even have a scoop to speak of inside and I'd dang sure want that restriction out. I vote for removal

 

Air flow should be the same just not forced into the EGR cooler. I doubt you will have any codes.

 

it will produce a code for no flw detected sorry to say. things we are looking at would be ebp and iat1 vs iat2. it will know.

 

The OP will not be blocking the EGR cooler just removing the scoop out of the up-pipe.

 

some how I missed the word NOT remove from the op.
In this case I just dont knwo what will happen.
