And that would be true. The MM Act does put the burden of proof on the manufacturer and not the consumer. The Federal Trade Commission recently put out a position statement that reiterates this because they saw a number of instances where OEM's were taking liberty with the regulation. The FTC decided to reaffirm that the burden of proof is on the manufacturer. The OEM is counting on the public to be unaware of the MM Act, or how it is to be applied. It is a very simple read. Not like some sort of Obamacare kind of paperwork nightmare. Most good legislation is simple.
Now as this pertains to ECM tunes, as long as someone doesn't go extremely goofy, any of the marketed tune products will not cause the engine to exceed it's design parameters. They don't want to get a flood of lawsuits on themselves for blowing up people's engines. And since most of, at least, the canned tunes that come in these products will not take any engine beyond it's design parameters, there should be no issues.
Keep in mind, the stock tunes are what they are because the OEM has to deal with a lot of owner issues. People putting in sub grade cheap fuel, not driving the vehicle properly and in fact actually being very abusive. The OEM's have to cover their bacon, so they are very conservative on how they tune the engine. Those that are more conscientious about their vehicles, how the operate them, and what they put in them, really have no worries using a performance tuning product from a reputable source.
Now, I am getting ready to do a Diablo tune on my 2013 Silverado that I bought late last May. Just wanted to get about 10,000 miles on the engine before doing it. I custom tuned a 2006 Jeep Liberty Diesel that I had and now my son owns. It was done under warranty, the dealer knew it, and there never was any issues. Dealer never even hinted that it was a problem, even when I needed a couple of glow plugs replaced under warranty. They knew about the tune because I told them not to reflash the ECM because it had a custom tune. They complied with my request. When you are confident of what you know, and you assert yourself in a firm, yet non asinine way, most dealers are not going to go out of their way to play these kind of games. Oh, and the Jeep dealer I referenced, is the same Chevy dealer that I got my Silverado from, so the brand had nothing to do with it.
All of this is why I have no problem with tunes, CAI's, custom exhausts, etc for anything I own. I use good sense and am primarily interested in efficiency as opposed to racing. I have tuned and customed out my commercial semi trucks (tunes, turbos, manifolds, etc) and my personal vehicles. Never lost a minute of sleep.

Yep, got lucky. Only 11,000 were made for the N. American market. Only cost me $500 more than the standard 3.7 V6. It is a 2.8L inline 4 cyl, cast iron block, wet sleeved, dual OHC, Bosch common rail fuel injection with about 19,000 psi at the tips, with a Garrett VG turbo pumping the air. Almost the same torque as my 5.3L V8 in my 2013 Silverado. It was EPA certified at 27 mpg on highway. I typically got 33+ on the highway. It had the 545 auto trans from behind the 5.7 hemi in it. My son owns it now and loves it. Fantastic ride. Many days, I miss it.

If you really know what you are doing, and what you are talking about, and do so confidently and assertively in a respectful manner, then most places will be respectful about it in return.

You really should learn more about how these things work; especially if your job is operating a dyno.
