This issue has been debated ad nauseum for years on every car and truck forum in the internet! Here's the bottom line...
Yes, technically modifying a factory tune can void your powertrain warranty. There are a few BIG differences in this application though.
The first is that this isn't a Mustang, Hellcat, Camaro or Corvette. If you blow the engine on one of those, the very first thing the dealer is going to do is check for an aftermarket tune.
Second is that this is a VERY strong engine and you're not talking about tuning it to the absolute max power by any means. And it doesn't have forced induction either. It's simply a somewhat industrial engine that's detuned in stock form.
Third is 5 Star themselves. They are one of the only "aftermarket tuners" I've seen that has actual Ford dealers installing the tunes and also has motorhome magazines doing reviews of their tunes. That's kind of crazy because not only do their tunes potentially void powertrain warranties, they're illegal as far as smog laws go. It's almost like in this RV world doing aftermarket tuning is given a pass, especially if it's done by 5 Star. That's absolutely NOT the case in the rest of the tuning world.
So MY opinion on the warranty and smog part of all of this? Don't worry about it. lol. Seriously, it's not like you're putting a turbo on it or taking the catalytic converter off. Technically putting headers, intakes and even changing thermostats is illegal. Is there a gigantic market built on people putting those things on their RV's? Yep.
