View Full Version : 6.7 Cummins

Hope I'm not making a mistake but trading the '06 5.9 auto in on a '12 6.7 manual trans. :confused0006: Pretty sure I'm going to miss my fuel economy-consistently gets 18mpg around town and 22 on the highway and haven't heard of anyone getting that unless they do a DPF and EGR delete. Would like to go that route and a better flowing exhaust but don't want to mess with the warranty. [16]

Anyone have a 6.7 and what do they think of it? And is it stock or done the deletes yet?

Buddie here in nelson bought a 12, manual from those guys in trail.. Thing got horrible fuel milage.. it shifted very ruff, and the turbo would loose boost between gears and lag the thing down hard. it was very very slow...

he buys a new one every 2 years from those guys, needless to say they took it back, and sold him a two tone brown auto.

Which he took to a spokane Diesel shop and got the Egr/DPi delete and some goodeis.. he is very happy with it now.

I drove a 2011 6 speed manual last year and thought it felt like a slug compared to the acceleration of mine but going from an auto 5.9 that's broken in to a brand new engine I figured it would be better after 10,000km or so. I also thought the manual trans engine was 800ft/lbs but Dodge site says only the auto's get the HO engine, manuals get the 610ft/lbs. Didn't see that 'til today. :mad: Looks like I'm going to have to live with it until I want to take a chance and do the deletes to it. Either way it's way better then a Powerstroke! :D

I got to see the inside of a 6.7L in school don't think much changed from the 5.9L except upping the displacement but probably all the problems are from emissions and other such exterior things they have changed cuz they are built pretty well.

Sorry, was away on holidays for the last week. Looked on their web site (Kootenay Chrysler) and don't see my '06. Wouldn't be surprised if it sold fast, was a really clean truck, 86,000 km on it. Give them a shout and see?

So 1600 km on the new Cummins and liking everything but the mileage. :D With the camper it's getting 14mpg (real calculations, not the trip computer), and 16-17 without around town. 5.9 got 15 with the camper, 18 around town and 22 on the highway. Powerwise the torque isn't the same, first 1200km it had nothing below 2100rpm but it hit 1300km and now it seems to pull hard from 1500 and up, pulls really hard in the upper rpm compared to the 5.9.

Can't wait 'til warranty is up to do the DPF and EGR deletes. [36]
