When I started to read the above post I initially thought it was going to be a legitimate post with some actual facts, but after the first paragraph I was wrong. This post is chalked full of wrong information right down to the reliability of the cummins. If your above post was referring to the 5.9 I would agree, but the 6.7 and it's emissions equipment does not support the legend. And the warranty of the Duramax and the Power Stroke is the same as ram.

I can say I got to spend some time with my cousin this past Christmas who works on these 5.9/6.7's and for some owners they had some very expensive bills last year.

Yes, the emissions devices did cause issues for the pre SCR/DEF Cummins just like it did with the 6.4L Powerstroke. The reason why it caused more issues for the Cummins is because they were over utilizing the EGR to meet the 2010 emissions back in 2007 while the 6.4L only met the 2007 emissions and NOT the 2010. If Cummins/Ram would have decided to just meet the 2007 emissions instead of getting ahead of themselves by meeting the 2010 then the issues would have been less. Still the issues are not that much different than the 6.4L had with EGR emissions failures. However, that all changed with Ram/Cummins going to DEF in 2013 for their pickups and 2011 for their cab and chassis trucks.

I have friends and family members that work at Ford dealerships too and I even worked at one. To say that the Powerstrokes don't have expensive repairs while insinuating the Cummins does is a false one. Fords and GMs have their CP4 issues while Cummins had their emissions issues before SCR/DEF.

With the Ford and GM CP4 issue it is not an issue of if, but when since it is a mechanical part and all mechanical parts fail. The difference between the CP3 and CP4 is the damage they cause when they fail and how sensitive they are to failure due to fuel contamination. When the CP4 fails(which all will at one point), then it grenades causing owners to replace entire fuel systems amounting to $10k repair bills to where it is just a simple HPFP replacement for the CP3 since they are not prone to grenade. Then there is the issue of sensitivity to fuel contamination. Due to how the CP4 gets it's cooling, it is A LOT more sensitive to fuel contamination than the CP3. So to say that there is only and issue with one while there is not with another is a 100% false statement.

Also, the 'seat of your pants" feel with the Cummins has more to do with how Ram tuned the throttle causing slow ramp up than the engine. This can be tuned out or fixed with a module like my BD throttle booster. Without my truck tuned, my neighbor and cousin who both have 2012 Powerstroke's even stated that it gets off the line with less input than their Powerstrokes with mine set at only 50% increased throttle sensitivity. It essentially increases ramp up to a more instant feel instead of the slow boost and fuel ramp up Ram tuned into the throttle. The power from the engine is there, you just have to bypass all the **** Ram did to nerf it.
