Is it possible to delete just the EGR and keep the other emission components stock?

No apologies needed. I’m not offended or anything. I just have different goals then you like you said. I want to hear my turbos spooling up. I want the added fuel mileage, got 38mpg on a 120mile trip with cruise set at 75mph from maine to nh which is fairly hilly, then 33mpg on the way back hauling ass going 90+Mph (that was in mexico of course

). I want to not being regening wasting fuel all the time and seeing 1,000+ degrees driving normally. I want the added peace of mind not having to worry about any emissions related problem. That is why I did my abc delete, not for 15 more horsepower. But I see where your coming from.

It also eases the CBU that chokes the engine and throws codes, My injector codes were fixed with Stanadyne additive and would highly recommend that stuff it also made it run much better, Currently it's just my EGT and DPF that are throwing codes along with the expected underboost issues.

My DPF has to go...

Just got the car running again with the new EGR race pipe and the JR Stage 2 tune. Wow, I wasn't expecting such a noticeable performance difference considering that I didn't do the full ABC delete. The car feels completely different now, much better acceleration. The gas mileage seems to be improved as well. Very happy that I decided to remove the EGR from the vehicle.

Will do the DPF/SCR removal when those systems start to fail but I am very happy with the car for now.

In the last month I have had my mechanic change the transmission fluid/filter/mechatronic sleeve, seals, thermostat, both diff fluids, transfer case fluid, glow plugs, glow plug pre-heating module, EGR delete, and all vacuum lines. I also changed the power steering fluid myself using the turkey baster method. I really hope that I don't have to put anymore money into this vehicle for quite a while, this has been a very expensive month of maintenance.

Removing the EGR would avoid having to worry about a cracked cooler, but as you say, tuners can adjust the tune for a specific hardware configuration.

OP, you can also remove EGR without a tune, but you would have to plug in the EGR valve and ziptie it to the side to avoid limp mode. You would also show an SES light with this method.

Doing an EGR valve and EGR Cooler delete very soon. I'm just waiting for the parts in the mail. Quick question...what happens to the EGR valve 5 pin connector? Do I leave this hanging by the side of the engine or do I have to plug it back in the original EGR Valve and zip tie the whole assembly securely hanging on the side of the engine?

Oh btw my vegicle is a 2012 E70 LCI 35D diesel engine. Thanks

Leave it unplugged.
