My buddy is buying a 6.7 andf thinks it is very sluggish in O/D when stopping on it. HE said my 5.9 felt like a rocket compared to this. it is a 6 speed auto 2008 big horn.
this 6.7 has 13k also could that be some of the issue?

DPF, can you just unplug it without any side effects?

thats what I thought as well. it is a 6 speed auto. I told him to try it with the O/D off and see if it is better.

it does have a jake brake too. very nice truck

The drop in rpms in 6th is insaine, If it doesn't downshift when punched, yes it is a slug. I think when I was drivin my buds it was at 1350 goin 70

he said it did down shift when he punched it and it was still a slug. when he gets a chance he is going to drive it with the od off. that should tell him if anything is wrong with the truck. I am guessing the low rpms are what does it. I also asked him why that would be so importatnt.

Turbo could be sooted up and not allowing the VGT function to work properly?

just to add the truck is completely stock, if that makes a difference

nope, no differece at all... Crap egr design does it.

The '08 6.7L we de-BlueTec'd in the shop last winter was such a slug while baselining that I had to pop the hood just to make sure there really was a Cummins in there somewhere.

your buddy must have a 3.73, cause i have the 4.10 and at 73mph im sittin at 2k rpm. but even then when i stomp on it, she downshifts.

I just drove it . good low end. a total waste of a good motor at cruising speed. no power just like he said. I wouldnt buy one if I test drove it.

id say the turbo is jacked because of the egr crap. mine seems to have good power in 6th even running stock

i have a manual tranny and in over drive i have plenty of power from 1200 all the way up when the truck is empty even when it was stock and i have 4.10 rear doing 70ish at 2k

the one he test drove last night was an 08 quad cab Blutech6.7 auto dually

he said he is test driving a 07 6.7 mega cab dually auto and this one has way more power all around, also drives and rides nicer. it only has 14 miles. yes 14.
he said he thinks he will get it.

is their a difference in the two motors? this one doesnt have blue tec emblems all over it.

---AutoMerged DoublePost---

I drove the 07 an hour ago. wicked. that o8 was fuct up for sure. i was wron on the milegae of the 07. it has 44 miles. not 14.
anyway here it is

i had the same thing happen when i drove a standard. it was sick compared to my 08 auto. its got to be the emissions stuff. i know they run real good without that stuff. mine gained more power after a few miles.
