Another Little issue

Since you have an 08 with less than 20,000 miles, I cannot believe it would be the MAF or throttle body. The fuel driver module is in front of your spare tire on a crossmember and you can see it if you lower the tire. Again, I would not suspect a problem there in an 08 unless you drive a lot on "salted" roads. If you do have a problem, it will have a "corroded" look and may appear to be distorted. If that is the case - replace it right now.

Again, a clogged fuel filter doesn't seem likely in 20K miles unless you fill up at stations where there's a lot of sediment in the gas.

Plugs & COPs? Maybe, but I doubt it.

Does the problem occur at all with the stock tune and, did the truck ever throw any codes? Possibly, there's a PCM flash update that would fix this and since you don't have custom tunes, it wouldn't hurt to ask your dealer about it.

I don''t see why Edge is referring you to PHP - they should only do that if you have a Gryphon.

Put it back to stock and haul it to a dealer, its still under warranty.
Drive it 50-100 miles to get rid of the p1000 code before taking it in.
BTW
What's your hex code?

I experience the same symptoms in my truck and only on #2 tune. It doesn't do it on tune 1 and 3. Since 2 is for towing, I just decided not to use it unless I'm towing, which isn't too often. And when running on #2, and the truck misses, I usually pull over immediately, turn off the truck and it stops the rough running for another two weeks or so.
