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.

 

I bought a 2010 mega cab 4x4 6.7 with the 6 spd in may and have put 12,300 miles on it already and love it. It's the best truck I've ever owned so far.

 

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.

 

When you did the EGR/DPF delete what performance aftermarket parts did you use? Would you have to replace the whole exhaust system? What exactly entails "removing" the EGR/DPF?

 

AFE exhaust of some sort - any DPF delete turbo-back exhaust will work though.

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?
