Decided to get my DPF, DEF and EGR Deleted in my truck, currently in the middle of putting the new exhaust back on. I just have a few noob questions. First off, will doing all 3 deletes at once have a negative effect on my truck? Second, when everything is put back together and deleted, Will my truck throw codes/go limp mode until I get the PCU Def codes written off? Third, I have a Bully Dog GT Diesel Tuner, will the stock tune that comes preloaded on the SD card write off my egr and def sensors? if not, would anyone know where I can get one if my tuner can do that at all. Anything helps!

Your BD will not be useable on a non stock exhaust. You'll have to get one from someone that does.

Would and SCT X4 unlocked and unmarried work? I’ve seen everybody like those. And where could i get a good tune for it?

Search online for people that still do that type of tuning.

I don't know for sure about some of the stuff you are asking as I have a 2006 and don't have the DEF issue but I did do an EGR delete. I used an SCT X4 to turn off the EGR so no CEL shows. Problem you may find is that the new firmware most most of the tuners out there including the SCT X4 have eliminated being able to turn off EGR function because of govt pressure I guess. I bought mine from Franchi Motorsports and he retains the old programming which allowed me to do what was needed. The owner is easy to get ahold of and discuss this stuff. The tuners he sells are unlocked and un-married. If you get an SCT X4 that has been used on another truck, you will have to send it back to them and pay $150 to get it unlocked/un-married and they will slap the latest programming on it and you will not be able to turn off the CEL.

Still won't work on a 6.7, he needs the DPF off as well.

Take a second and explain what you mean for me and the benefit of the OP. Are you saying the SCT X4 with older firmware can't turn off the DPF? (not sure what that is anyway) Great to tell someone they are wrong but an explanation is always in order.

Well, before you get snippy, you're in the 6.7 section pitching used X4's, as you have in other posts in other sections, so. And, I didn't say YOU were wrong, I said still won't work.

For a simple explanation, he won't be able to turn it off himself, he needs a custom tune for it to be turned off. DPF is Diesel Particulate Filter, all new diesel's have them, you wouldn't know because your 6.0 doesn't have that.

Not getting snippy; just asked for some explanation of why the SCT X4 tuner wouldn't work. I doubt the fella has much knowledge and guess I was asking for both of us. I did mention I didn't understand some of the tech on the 6.7 and suggested he contact the seller in the link I posted as that guy does understand what can be done and what can't. Thanks for your explanation. Wasn't trying to be snippy.

You can use an SCT X4. HOWEVER! you need a CUSTOM tune to disable the emissions equipment. Off road use of course. Who sells custom files? Alot of people. Just look it up online. Sct had a bad fallout with the epa. They got fined for the old 3015R tuners that would disable 6.4 emissions. Since then, the latest and greatest update on a X4 will not even allow you to disable the EGR on a 6.0. Everything emissions related will now have to be custom tuned.

EZ Lynk

Decided to get things finished up with a mechanic. He will be putting in an EZ Lynk tuner in with a custom tune to delete my DPF, Def and EGR systems, and he is putting in me SD EGR delete kit for me.
