Tough call. OP says they ran a canned tune for one day, then a BBR for a while, then the Lund tune. Car started smoking after running Lund for one month. Could it have been previous damage? Sure. Could it be from the Lund tune? Maybe. Do we still not know what causes #8 to go boom? Definitely.

But did you post about 1 issue, and only 1 issue? This guy has been everywhere trying to start some kind of anti-Ford MT82 posse, including on blogs and on blog posts that have nothing to do with the 5.0 transmission.
I remember his threads. And yeah, he disappeared without a trace or any more updates to his car issues. Funny how even specifically said to me his initial problems were not even due to the Chinese tranny, he wait it was all clutch and flywheel. But then his story started changing more and he began to sound like he was blaming the Chinese made tranny again.
Reading the story of the guy who is making a tremendous deal about his #8 cylinder does share some similar actions like jmatero's.
And though I am a serious propent for consumer protection and strongly agains summary denial of warranty work, I am damn curious why that guy did not also try to attack the aftermarket guys fur his ****ed up car?
As I always say, if the mod or improper installation of the mod did indeed ruin the car then yes you should be denied warranty work. And on the side of consumer protection, the hack aftermarket guy should be forced to pay up. Now if the owner screws up installing it, then of course no one, Ford or the aftermarket guys, should be blamed. The costs should therefore go to the owner because he screwed up his own car when the car or the mods would not have otherwise caused any problems.
Has nothing to do with the year of the car it's just by 2012 tuners figured out to stop turning off the knock sensors (Bama) cough cough.

I have a very early 2012 model, I got it in may of 2011. I put a CAI and tune on it within a week of buying it. I still haven't had any problems with it. I had an SCT tune, a BBR tune and a Steeda tune... still using the steeda tune and liking it.
There are a lot of suggestions that are plausible for what caused the damage. Some say it happens after extended high MPH runs (like over 140mph) some from using low octane gas. some blame the tunes themselves, (knock sensors).
I don't think we'll ever know, but I haven't heard a report of an issue in quite awhile.
As far as the OP goes, as others said, it isn't a spark plug issue, that is certain.
