2007 Dodge 2500 6.7 Likes or Dislikes
I'm looking into getting a 2007 2500 Mega Cab 6.7l. I was just wondering if anyone is haing any issues with it? Do you like it or hate the 6.7l? I was reading that there are a lot of problems with the emissions. Specifically the Diesel Particulate Filter (DPF) and the Exhaust Gas Recirculation (EGR) system. Have these issues been fixed yet? Hate to spend 38K on a truck to find out its $hit.

If you live in an area where emissions testing is done, go with a 5.9. If you don't, and don't mind removing emissions control equipment, the 6.7 is a beast.
Keep in mind that you'll probably get 12-14mpg with the 6.7 in stock form, maybe 18 cruising down the freeway at 60.
With the 6.7 and no EGR/DPF, expect those numbers to go up to 16-18 around town and 22+ cruising at 60.
The EGR injects carbon deposits into your engine. It's not good. The DPF chokes the exhaust, and then sucks fuel to burn the soot off (regen).
H&S's dyno sheets show 495hp/1100 lb-ft after doing the egr/dpf delete, exhaust, and intake on a 6.7 with their tuner.

AFE exhaust of some sort - any DPF delete turbo-back exhaust will work though.
H&S egr delete
H&S tuner (black maxx in my case)
H&S fuel rail shim kit
and S&B intake

Removing the DPF means you're replacing that chunk of the exhaust pipe with straight pipe, and getting rid of the sensors and air/fuel/whatever lines that plug into it. Removing the EGR on a 2007.5-2009 means unbolting all of the crap from the top of the engine and plugging the holes. Removing the EGR on a 2010+ can be done simply by flipping a switch in the software with a programmer, or by removing it completely.

I know that this might be a stupid question, but did these upgrades increase your fuel mileage? On the web sites they are adamant that you do not ask them that question. I see that Horatio said that the mileage increased. Can you actually confirm first hand to those numbers or are they an estimate?
