Are 5.0l engines improved?

Why would anyone expect ford to pay for an engine failure when someone has a tune in their car? Ford designs and stands behind their engine when operated with their "tune". If you vary from that, that's on you, not ford.

Look at the conversation between me and the other guy. My question you quoted was a rhetorical facetious remark. Come on man! I'm a mechanic who mods every car and truck I've owned for the last 14 years and know what voids a warranty. Good grief. I'm not an idiot lol.

Because otherwise their tune business would have died if they didn't do something since they were one of the tuners that had failures reported. I haven't read it in a few years but as I remember it they were very specific to warranty problems only caused by their tune such as detonation - not for defective or weak (or melted) factory parts. You'll have to read it yourself. And obviously they (and others) backed their tune down from what it was at first. Some say the tuner's problem was at first they disconnected the knock sensors. But that doesn't explain the (relatively few in comparison) factory failures.
Whereas personally I would never buy a tune from Brenspeed as they left some of their tune customers who blew #8 high and dry. There's a long thread here about one guy's experience through the whole ordeal. Brand new car (12), brand new engine, thousands for a rebuild (on top of his new car pmt), zero help from Brenspeed.
Remember these are powdered metal shake and bake hypereutectic pistons. If you look at the fail pictures many of those #8 pistons were melted at the lands on the exhaust port side. Not all had damage to the top. Others had damage to the top of the pistons from detonation. Why only #8 and not #4 also (both back of the engine compartment) I have no idea.
I would guess that the new coatings help withstand heat better (perhaps also strengthen the piston to withstand mild detonation better?), and the redesigned oil control rings (with added ports in the lands) help cool the pistons - perhaps better than the under skirt oil squirters (although there may be other reasons for their deletion [Cost? Windage prevented peak performance at high rpm? Perhaps inconsistent 'squirts' at high rpm? Oil pressure issues at high rpm?
]). I have never read where they redesigned the cooling jackets in the head or block for the 13/14. (Although Ford does mention some head changes for the 15 5.0.)

Brenspeed has a terrible wave of horror stories stay away. Mainly issues with guys blowing there engine and them not doing anything. I have a guy at my plant who is a huge fanboy and I just shake my head lol. If u tune go with the big three I like to call bama, steeda, Jon Lund,

I have s 2012 GT 6so manual. I have a 93 octane race tune. LT Headers, magna Flow exhaust. I have close to 43,000 miles on mine and have had
not one problem with this super builder 5.0 . I runs just as strong as the day I ought the tune in which was at 3000 MILES. I change my oil every 5000 miles. I did have a dyno tune right after installing the 93 race and the tuner did have to change the A/F setting. It was running a little lean .but it's been a great car for me!!
