Noooo, don't jinx us w/ the Mazda curse! Hush yo mouth. Hopefully lessons were learned and corrected.
With all due respect Shaun didnt figure out a "work around" on the number 8 cylinder problem. The problem stemmed from tuners applying 3V tuning techniques to the new 5.0 Coyote. (adding tons of global spark, turning off knock sensors and leaning it out). Competent tuners (and shaun is one of them) tuned the 5.0's the way they are supposed to be tuned and the cars run great without applying those 3V tuning techniques. FWIW our car still holds the stock longblock bolt on N/A stick record for the last 3 years with a 10.88@125mph.
there indeed is, this is why choosing your tuner is more important than ever. The days of tuning something and hiding it are gone.

The number 8 problem was also made worse by the block design as well. There were several changes made from 11-12 in just that area. (head bolt size/length etc..) in an effort to alleviate the problem.
As far as how safe tunes are with these cars goes I can tell you that the internals will hold alot more then people think. Its RPM and detonation that will kill this engine over the long haul. If your too agressive with the timing, start limiting or turning off the knock sensor then you will wind up hurting stuff but for the most part all of the tuners who have had hands on this car since it came out will most likely follow suit with making the tunes safe and reliable.
I know for certain that our daily driver "torque tune" is very safe, keeps alot of the factory calibration protections on and has conservative spark and fueling maps but also yields great seat of the pants feel as well as power in the entire rpm operating range.
And your very right on one statement inparticular... Time will tell on how, when, who and by whom these engines to grenade but sometimes you have to push the limits.

lol I ran BTR on my Optima for 30k w/out issue - aS FoR that other company, let's just be thankful he's not here.
advising members an Eco engine wall's blown out is not spreading fear for nothing.
