Unplugging EGR vs. EGR Delete

With the EGR unplugged, will it still eventually get gummed up? If so, how do I keep a watch for that? @PURPFOX says BAT's will go up. Are there other indicators I would be able to see on my AP?
 
Well if EGR is closed, will BATs will go down since no more hot air into intake. And it is safe to say all the crap that is usually flung through it, will get backed up onto the piston.
 
So after unplugging the egr. I only throw p0403 not p0401also my stutter under boost seems to have disappeared. Denso ivt22s are going in this weekend just to be safe.

for some reason, i was thinking that EGR delete actually raised BATs...which seems counter intuitive but that's why it stuck.
 
When i had mine unplugged i would get a random misfire code. I had this issue for a long time until i deleted the egr with a basic 20$ delete. That fixed my random misfire. Once i "got a guy" for inspections NCE on visual stuff so that motivated the delete as well as a pima time cleaning my valves.
 
So fwiw, a loophole my bro in law told me about concerning emissions here in Wilson county, tn. His jeep as had a CEL for as long as he's owned it. A month before his tags expire he goes to the county clerk, changes his vehicle class for a few bucks more than tags alone and they give him a new plate with fresh tags. So I'll be doing that since I'm gonna de-cat mine.

Not to derail but unplugging the egr works great in conjunction with a coolant bypass. The only thing that is needed for that is a 3/8th barb union and is completly reversible. Or you can just reroute the primary line that leads to the water neck down to black coolant pipe that sits where the trans and block meet. In serious situations where some customers have seen 140-150* bats i have seen the temps drop to 120-130*, rise slower, and rebound faster on cruise. (coolant bypass and egr delete/unplug performed at the same time)

Correct me please if I'm wrong, but with the EGR piston closed, there is no flow. Without flow, there is nothing to carry the junk to the piston.

Correct. The default, unenergized EGR position is closed. That's why I run unplugged most of the time. To me, I see no need to EGR delete unless you need the extra room for a bigger turbo, like a MUCH bigger turbo. My EGR is still intact with my BNR S3.

And I can't say for sure, but I'd agree with you about the flow not going to the EGR portion of the EM. All of the exhaust would head into the turbo. That seems to make sense.

There is some small flow from IM vacuum/boost cycles plus vibrations, so junk can be carried down from EGR tube.

I did my full delete, it's not like it's hard to put back on for emissions, one less thing for coolant to flow through
