It depends on your year, as I understand it, the early years can be unplugged and not throw a code, and after about 2004.5 (someone correct me if I'm wrong)...it'll throw a code if unplugged. In my 05 it throws a code if unplugged, but when I deleted mine, I just took the valve out and left it resting next to the oil filter housing still plugged in. No codes or issues at all. Also, a custom tune can turn tell the computer not to look for the egr valve, and therefore not throw a code.

While we're on the subject, if your egr cooler went out, it's likely because your oil cooler is bad, or going bad (starting to clog up)...a rebuild or replacement is usually necessary, I flushed the crap out of mine still in the truck, lots of distilled water and "restore" and "restore plus"...there's write ups on how to flush it...anyway, then the use of an ELC coolant is recommended (I used Rotella Ultra ELC). It doesn't gum up the oil cooler the way the ford gold coolant does. Then I added a sinister coolant filter...it's relatively cheap, and my temp delta's have been great since, without changing the oil cooler. I may have gotten lucky...so I was told by several on here who reamed me for not changing the cooler while I was in there. Anyway, good luck. Hope it helps.

if you dont have inspections, go with just an EGR delete and leave the EGR valve in. all it will do is cycle on and off, but wont do anything, obviously because the EGR cooler isnt there. with mine being an 04, i installed the XDP EGR delete and took the valve out completely, and installed the supplied blockoff plate. if you have an 03-04, it wont throw a code. if you get a programmer, you wont have to worry about it anyway.

I noticed slightly cooler egt's...possibly slightly faster spool up, but mine is an 05, and it has "the dreaded scoop" in the up pipe to direct flow into the cooler. The thought is that by sending that much more air to the turbo, instead of into the egr cooler that it spools it faster. That's probably true, but it's not a light switch, on/off difference, it's subtle. I don't know if earlier years with out the scoop would notice anything.

Be sure to update your turbo drain tube and whatever else needs updating while you're in there. I'd also ad the blue spring while you're under the hood, it'll be easier without the cold side cac tube in place. I might have mentioned it already, or someone else might have, but I've slept 6 hours total over the last 2 days and can't remember...but add a coolant filter if you haven't. Clean coolant is imperitave if you're going to run a stock oil cooler. Even if everything is good now temp wise...I'd still ad one. Cheap insurance. There's a reason tractor trailers have coolant filters. Anything with a engine oil cooler needs a coolant filter in my opinion.

Depending on your stategy, the EGR valve is REQUIRED for proper VGT cycling. Considering how Ford butchered our ECUs when they "serviced" our trucks, I'm more concerned about VGT cycling than codes/lights.
