Delete DPF, Delete Warranty?

[Dr.Evil]

I recently picked up a 2011 ex cab lariat and I love it. I've been reading a lot about the DPF delete, and the better mileage it yields. I get around 15 around town, and 17-18 on the highway. I would really like to see 20+ on the highway and 16-18 around town. From what I have read, this really isn't out of the question with a DPF delete and tune. My only hang up is the warranty issue. This is my first vehicle that I've ever had a warranty with, and don't want to jeopardize it. Has anyone actually taken their truck in for warranty work with the DPF delete? What did they say about it? I really don't need the extra power, just better mileage and for it to actually sound like a truck! I swear this thing sounds like a Prius at idle

Is it possible to just pick up a second ECM to swap in if something happens to the truck and warranty work needs to be performed? I'm assuming a new ECM would be pricey, if you can even buy one.

Anyway any input would be great. Thanks.

Tuning will give you a small increase in fuel mileage. Don't expect to see anything dramatic. Tuning is more for horsepower and performance. I have run spartan, h&s, and KEM tunes. Not really that much of an increase in mileage, but it sure is impressive and you won't want to go back to stock. As far as sound goes, other than making it sound like a giant hair dryer, there is not much you can do to make it sound more like a "truck".

Put a muffler it will eliminate that hair dryer sound and still give it a nice rumble. As for the warranty just put the emissions stuff back on and tune it back to stock and take it in.

Doesn't the ECM datalog anything that has been done to it? As soon as ford scans it, they will see that it has been chipped, right? Thats what I am worried about.

Thats what they said about the 6.4 and we never had any problems. According to Spartan, during a flash EVERYTHING is wiped and rewritten. All that will happen after a flash is a P100 code I believe. But that code is thrown whenever the battery cables are removed.

Thats my understanding. When in doubt PUNT!

The warranty issue has been the great debate for some time now....just like oil threads.

If your truck was tuned, and you return it to stock, a Ford engineer may or may not be able to detect some tuners.

I have it on good authority that if the engine suffers something serious, the dealership is required by Ford to dig deeper into the nature of the failure....including Ford having a regional rep come out to inspect.

The 6.7 is being watched very closely by Ford....so you can bet they will have no issue with sending someone out to look at catastrophic failures.

I have nothing against tuning.....just make sure you have the financials to cover a repair if Ford finds something and denies the warranty

I want to tune mine soooooo bad. I have a new S&B intake sitting in the garage for it. May just put it on for the heck of it. I said I would wait til the warranty was up, but not sure I can make it that long.
