My new exhaust helped the fuel economy and turbo lag. Not to mention at throttle the motor is even quieter (louder turbo whine now) But the diesel noise is down more.

Cant wait to get my software update, id immagine im already at the 800lb tq mark with my huge exhaust. Maybe after that and my new intake im gonna get ill be pushing 900

 

My 400hp and 800lb of torque is sitting at the dealer until I get home to pick it up in 2 days....built 08/12.

 

Now that is something to look forward to returning home for.

 

My 2011 pulles my 10k 5th wheel with easy compared to my 2005 (which I thought was good)

I'm going to wait for the flash to get any mileage reports. I can't see getting more horsepower AND better mileage also.

Read up on aftermarket tunes over the 6.0s and 6.4s.. All the lower hp gain tunes always gave more MPG. If you smash it more often you will get worse but your normal city putting almost always get better

 

Ya... I actually completely forgot about what a stock 6.4 is like hahaha. I have been spartan tuned for so long now. And that tune addresses the lag, acceleration and the MPG. The new tranny is def a big seller for me... the flexibility it has + having 6 gears is great. But stock 6.4 vs 6.7, I can say there is no discernible in the noise level. I had my 6.4 right next to my buddies new 6.7 and we both agreed.

 

Are you kidding me? If this is true then either there are DRASTIC differences in the noise level of the 6.4's, or the same for the 6.7.

The 6.7's that I've driven (2 now) are _night and day_ quieter than my 6.4.

 

radzer0, I'm interested in your mod's at some point down the road,Let us know which intake you use! Also let us know if Ford gives you any problems with the exhaust mod when you go for the re-flash! thanks

 

What Exhaust did you put in?

Also I picked up my 2011 F350 which has a build date of 10-11-10. Do you think the reflash was done already?

 

yes..........

 

Any way of checking to make sure?

 

start the truck...put it in drive...press the plus button on the shifter and the gear list appears on the right side of your info center...shut truck off...restart truck...if thr gear list is still there you have the flash...if not, take it to the dealer and ask why...with your build date, it would have the flash but it may fall into the ranks of a few that need an update. Does your trans shift nicely when the truck is cold?

 

On mine the other day, the numbers were gone. I hit the plus and they have been back on since. Weird.
