How has it been running, aside from the less efficient fuel economy?

I have only really pulled one time with it since the new turbo and that was with my 12500lb camper. It did really fine.. I have not chipped it yet but its loaded with power.

I was getting 11 mpg pulling my camper before the turbo change... I have not pulled it since the new turbo unfortunately. Both of us have been diagnosed with cancer in the past two years and treated. I think we are fine now just waiting to get time to travel again.. I know that the mileage on the road without the turbo dropped about 2.5 mpg.

I'm sorry to read that after making so many different trips in for this to be looked at there has not been a satisfactory resolution for you. If we can follow up with your dealership on this, please send us an email at socialmediagm.com with more information (your name/Edmunds username, phone and address, the last 8 of your VIN and current mileage, the name of your dealership, and number of times you've been in for this same concern). My coworker Christina will advise you further.
Thank you for your patience, and we look forward to hearing from you,

You might take it to a place that does over the road (the big semi's) tires and have them check tire balance. I don't think tires are covered under the warranty. Happy hunting.

I have 2007 chevy 4x4 dura max with a milage at about 12 miles per gallon. Was wondering if this unusual or not for that truck I was hoping for much better than that.

I am very disappointed after owning my dmax for 4 years and only having 22000 miles on it. I get 17.5 mpg empty. I pulled my dads camper to New Mexico this week and pulled it fine, but got 5.6 mpg both ways and it did not matter if I pulled 65 to 75 mph. I thought it was because I pulled it to mountains full of gas and water but empty on the way home and was not any better. The camper only weighs around 7000 lbs. called the dealer and they asked when I had changed fuel and air filters and how much the wind was blowing. The 6.7 Ford is starting to sound nice , although my dads 2012 duramax gets 12 pulling same trailer
