I'm not convinced that it's a regen issue. Have you checked engine oil/coolant temps. If they get 30 degrees apart you will get check engine and reduced power. Make sure both temp sensors are connected securely. I would suggest you purchase a subscription to Forscan and load it onto a laptop so you can monitor engine functions when travelling down the road. You can force your own regen with Forscan.

I had a truck that was doing frequent regens. I put it on the road and drove it about 120 miles and it cleared itself up. Not only does the regen have to turn the soot into carbon but it has to be blown out of the converter to clear it. Sometimes short run regens aren't enough to clear it. As far as a egr filter. I am not aware of that. I do have a couple of egr valves in the shop and I will look. I may even still have a maf. I will look tomorrow. FWIW, I would still get the Forscan package. It would be the best $50.00 you can spend for what you get. Around $30.00 for the OBD adapter and $20.00 for the multi year subscription.

I did look on the engine for an EGR filter and didn't find one, even though it is listed on Ford parts online. Ours is the earliest 6.4L (with a build date of 08/07) so maybe that was added later. With the system stuck in Reduced Engine Power we aren't going to chance a long sustained highway drive to try and clear it. The computer completely shut everything off 4 years ago and stranded me in the middle of nowhere in the middle of the night without a phone because of an EGR failure. Thinking we will replace the DPF and try to treat it better until we can find something to trade for. No trades welcomed for deleted trucks in our area. I have only a pretty old Windows 8.1 notebook that I am downloading the Forscan on, will see if it works. Placing an order for OBDLink® EX adaptor.
I didn't see anything yet about the subscription fees, but that sounds pretty reasonable.

I'm running an 08 1 ton and I have no EGR filter. My laptop for forscan is windows 8 and runs out fine. The ELM that you chose will be key to success. Choose wisely.
Spend some time and pay yourself to read up on forscan, it will save you on the road as well as at a shop. I carry the laptop in the truck as you would food, rations, and blankets. It's a go too.

So, UPS delivered an OBD adaptor today and I hooked it up to the pickup and ran the Forscan program. I haven't had much time to learn the program yet, so didn't go very far. The initial log run showed DTCs in PCM of P246C-FF, P2463-FF, P0671-FF, P0672-FF, P0673-FF, P0674-FF, P0676-FF, P0678-FF, P2452-FF, P2263-FF, and P1000FF. Lots of junk going on there. I think I figured out that six of the codes are for glow plugs on all cylinders except 5 and 7. The rest I think pertain to a clogged DPF. Plan on getting a different DPF and learning more about using Forscan. I did see a software date of 06/28/12. I imagine that is the latest update?

I think my unit (Forskin) has the same update date area. I know it sounds old but, that is the end of the rope for troubleshooting our systems.
Anyway, Instead of diving deep into your pocket on a maybe, why not go a cheaper route. Buy a test pipe with bungs for the EGT sensors. Or you can get one un bunged and just leave em hooked up (important) and wire tie them to the frame. That's what I did many moons ago and all my systems are fine.
Give that a whirl. Write down your stored codes and clear them. Make your choice of changes and rescan the rig. See what haunts. If you drop codes but some persist, you will narrow a problem or just resolve it.
Are you in an emissions testing state? (Update your profile to share where your from, helps)
BTW, the glow plug DTC's could go away as soon as the truck is up and running for a bit to scrub the carbon if the DPF is plugged. 1 kill at a time.
