It seems to me these engines have either a weak valvetrain or a lot of bad quality parts got past whatever quality control procedures are in place at the engine assembly area.
In EITHER case, these engines seem to be failing a lot more than what I remember compared to the 4th gens. There were a ton of heads and cam cars out there and I don't remember seeing all these failures.
So, due to this, I don't think a tune is worth the warranty loss. It's too much of a high risk for a moderate increase in power.
I'm watching these threads very closely to try and pick out where the common root causes are. This is so that when I mod my car and void the warranty, I know exactly what weak or likely-to-be-defective parts I need to replace.
