Keep it stock until the warranty is up unless they can have the money for when something goes south. deletes now days on these trucks arent cheap either. To do DPF/EGR delete itll take more then just a new exhaust and delete kit. there are alot of sensors just like the 6.4 that have to have a tuner to turn off otherwise the truck wont run.

If anything they make some mild DPF on tunes now you can run with less risk as it can be removed easily. There are alot of stock 6.7's running around easily past the warranty with minor issues a best. biggest ive seen is grenading the turbo if its tuned too hot.

 

Thank's guys for the info...I think they decided to leave it alone for now and save the money for some tires when needed. LT275x65x20 Michelins on now and have about 30K left in them.

 

Nice truck! I just saw this ... So I am late LOL

I always chipped or messed with the gas engines just to get power. The 6.7 has way
more power stock. It even will out accelerate the Chipped, with headers- exhaust and geared F150
Me...! I only messed with the looks and made mine more off road friendly.

The truck looks real nice hows he doing now ... two more months and more time driving.
Mine has 30,000 miles since new. I have made two trips to Reno area. I get
3 mpg better than the F150 along with much more power.

 

Son in law is really loving the truck....makes his 50 mile a day commute fun! The truck pulls the 8K pound trailer easily and still get's good fuel mileage. The 6.7 has been amazing so far...powerful and quiet!
