I just got a 2012 F350 dually 4x4 6.7L powerstroke. And I have a 2004 Excursion 4x4 6.0L powerstoke. I know to expect a turbo lag but my 6.7 lag is waaaaay longer that my 6.0 is that normal? Both stock no up grades my excursion is sitting on 37" tires and pretty sure 0-60 would take the 6.7

 

There is some lag because of the emissions.

I know I felt the same thing when I traded my 6.4.

The 6.7 is slower on take off but it gets going then picks up faster after that.

I still think my 6.4 would beat it.

 

I've had 2 6.0 Excursions and now two 6.7 SD's...

The last 6.0 was tuned and would do very well, but it's somewhat like comparing apples and oranges imho...

Not that I care about comparing a 5 year old tiring Excursion I don't have anymore against a brand new all the bells and whistles Platinum...
but I got the vehicles for different jobs...
the Ex's hauled people, the SD's haul 5'ers

the @ 800 lbft torque @ 1600 rpm stock numbers are higher than the 700 tuned on the tuned excursion...

(Oh, and I don't compare my wives against each other - they both were fine at the time !!!)

 

Now that statement really shows a man who is willing to live on the edge...LOL!!!!
