Hey y'all
My wife bought be a 2006 f-250 as a wedding gift.(don't know if she hates me or loves me lol) it has ARP head studs I'm about to put on a 4" turbo back exhaust and Egr delete. My question is I've seen people saying that deleting the egr keeps the fan clutch from engaging. Will a SCT tuner fix this problem or just turn the check engine light off. Thanks a lot for all y'all do
The EGR delete is getting rid of the EGR cooler. The (exhaust) output of the EGR cooler is what is regulated by the valve. No cooler/no output. Your valve will be valving with nothing to valve.
You should know that the PCM monitors the IAT (Intake Air Temperature) sensor to see if opening/closing the EGR vlave causes the expected increase/decrease in intake temp. Your deleted system will obviously fail to meet the criteria.
The model years react differently. Given your model year, it will likely set a P0401 code and - perhaps - even set a CEL. I believe that this can be tuned away. It's no big deal either way, if it doesn't bother you. Just FYI...
An alternative to leaving the valve plugged in would be to get the 1997 7.3 fan clutch. It's a mechanical clutch so the computer doesn't control it but warning since it has a more aggressive lock up you'll hear it more than the stock clutch.
Here's another potential issue though. Some strategies have to see the EGR valve for the turbo to work correctly also. Better off to just leave the valve in place and eliminate the cooler which is the real problem anyway.
03 EGR coolers have tubes and 04+ have fins like you'd see on a radiator. Basically, coolant flows around the fins or tubes that are inside the cooler to cool exhaust gasses.
Would leaving the egr valve in place cause more carbon build up? I can imagine that if the carbon in the exhaust has something cling to like a valve it would cause issues with flow
The technical help on this forum is first class. BUT the real question is how did you get your wife to give you a truck? We all could use some pointers with Xmas coming soon.
But in regards to your original question, the best option would be a egr cooler from bulletproof diesel. If you don't go that route and do a delete, a cheap one will work fine, they're all pretty much the same. Hell I had a $30 delete on my truck for years. You will need a custom tune to turn off the check engine light if it bothers you, but custom tunes are a great addition to these trucks anyway.
The 7.3 fan kit from bulletproof diesel, while not "needed" to delete the egr, it is a very good replacement for the stock 6.0 electronic controlled fan clutch.
So what is the purpose of the egr eliminating spool? Use that and the 7.3 fan clutch? And completely eliminate the egr vavle instead of leaving the egr valve plugged in and in place. What is the better option
They are all different variations of the same theme. An EGR delete gets rid of the EGR cooler. Some people live in areas that do emissions testing. If they don't want a functioning EGR system, they can install a hardened cooler and then plug off the valve with a spool. The hardened cooler is necessary because a failed cooler can still leak coolant down the up-pipe to the exhaust manifold.
