Well I could only stand it for a week.
My strong running 07 GMC Denali crewcab shortbed completely crushed the Super Duty in any acceleration comparisons! I was honestly disappointed with the acceleration power of the stock 6.4. While I didn't buy the F-450 Dually to do 0-60+ sprints all day, every day (a big 5ver toy hauler is in our future) I do like to have fun and feel hp/tq at times!
5 days later I orderd H&S Black Maxx DPF/Cat delete AFE CAI ..... It took 3 of us less than one hour to install and as they say: The rest is history!
Re-mached with the 07 Denali and COMPLETELY different story and out come .... The tuned F-450 now pulls away at any where shy of tripple digits!
I am very happy with this truck now. I just have to learn to click 'er down a notch or 2 when towing. I have towed more than the Denali ever could have towed, and I'm getting better mileage and towing safer too!
I have towed loads of:
#3500 (honestly didn't feel it)
#6500 (towed well but hit high EGT with WOT pulling a grade with HOT tune)
#10000 (Knew the load was back there but felt the truck didn't even struggle and was in control 100% of the time)
Looking forward to towing the #18000 5th wheel toy hauler.
