Go to the dealer with engine damage or a blown tranny and see what they say. If you chipped/tuned your engine, they could easily say "no warranty, your problem". The MM Act means diddly squat in real life. People point to that Act like its their life-saver when something goes wrong. It will be up to you to retain a lawyer and file suit under the act to try to recoup your losses. Meanwhile, for several years, your truck is sitting there unless you forked out the $$$ to get it fixed. Then you get to pay your lawyer, pay the experts he hires to substantiate your claim, and whoever else you'll need to advance the case, and hope the court believes them over the experts that Ford has. Ford is not shy about denying warranty coverage on a modified drivetrain, after the 6.0 PSD fiasco that cost them many millions when people chipped that engine.
Not trying to be argumentative, just stating some real-life facts. Also, you may not even be able to advance your lawsuit due to a clause in your purchase agreement. In many states, buyers are required to submit to binding arbitration before filing a legal action. A lawyer may think he can find a way around that, but I'm going to borrow a phrase that a local lawyer uses on late-night TV commercials: If he promises that you'll get paid, you're getting played.
Nice truck, and that 6.2 is plenty powerful as it comes from the factory. Like others, I wish that Ford would put a boosted 5.0 in it, or even the 3.5 Eco. I'd be first in line when the aluminum Superduty comes out later this year.
