Yeah, that is pretty much what I ordered. As to the EGR block I'm not 100% sure if that is needed if the EGR is deleted from the ECU. Perhaps someone with more knowledge can weigh in? It may depend upon if your EGR is currently operating or stuck (and whether stuck open or closed). At any rate I figured I can do that later if needed. No reason to shotgun a bunch of changes especially when I'm in new territories anyway.

Mine was replaced about 15k mi ago and is not stuck. After monitoring via DAS I would just feel better w the block off. It seems to change position quite a bit under different variables. After emailing back and forth with Malone, it seems most just leave it in place. I remember asking them if a used ECU could be flashed, but they said to use the ECU from the vehicle. I’m not sure why though.

Likely because the ECU installed is programmed for all variables installed on your own unit (including software revisions, etc). Same model and year does not mean same hardware and firmware installed on all components. To use a different ECU you would still need to pull and read yours to ensure all variables from the new ECU matched your existing. If.you have to pull and crack open the ECU anyway, why do that to 2 of them?
Makes sense. Idea was to just have ecu flashed and ready to swap to decrease downtime.
Also, I don’t think you’d be able to gut the cat without cutting open. At least on mine (2010 gl350) there’s a sharp 90* bend just before it.

That's what I have heard as well. I'm sure if one is ingenious enough it could be managed, but I ordered the delete pipe just to make it easy on me (and to ensure I can go back to stock if my region starts emissions testing again).

Just received a notice the KTAG is being delivered today. Will try to get some unboxing photos posted be the end of the weekend.
I won't have the BDM frame until next week, so cant program yet but hopefully I can play with the software to get a better idea how it works.

Different issue
Well I thought my issue was my DPF, it was actually the cat. Which is way easier to hollow out than the dpf. Cleaned it out, unwired the O2 sensor on it and it runs amazing. I have a check engine light but no limp mode. I’ve driven it about 700 miles since and no other issues as well as 23-28 mpg at an average of 80mph. I do plan on getting it tuned and also hollowing the dpf.

I did it by drilling holes with a 2ft concrete bit and a hammer drill all over and then connecting a 1/2” swivel to my locking 3ft extension and just let it beat all round inside and it broke it all up. Probably took a total of an hour to hollow it out.

Great ideas. Unfortunately I already ordered the delete pipe. At least I can revert back of needed.
Question: how long did it take to unbolt and replace the DPF from the exhaust? I presume just a bolted flange on each end?

I will likely hire an experienced tuner to make the file for me (pull and read my ECU, send then the file, they send back "tuned" file, then wrote that back to the ecu and re-install).
This will allow me to push the original back to the ECU if the tuned file has problems or if I ever want to go back to stock.

Found this company last night, looks pretty good. ~$140 per credit, though it says excl. tax, but then doesn't charge tax on the checkout page (2 required);
Dyno Chip Tuning Files
This one offers higher gains, and runs about ~$120 per credit w/ tax (also 2 required for stage 2 w AdBlue delete);

I know this is an old post but I'm curious if you were able to hollow out the dpf and cat with this method or just the cat?
