The whole #8 issue was a freak thing that can happen with any other car. Every machine has it's weak points. Just becaues #8 or whatever cylinder blows doesn't mean the engine is weak. It just means there's a variable to consider. Unfortunately, sometimes they're just pushed to the limit and things go boom.
We live on the planet Earth. Unfortunately, as much as the hipsters and general internet users would think so, NOTHING will ever be perfect including Wall Street, my inability to stop farting first thing in the morning, and yes, modern engines including the Ford Modular Coyote. The Coyote motor isn't the only engine ever in the entire universe to have popped from a tune.
Jesus, we are getting 30 or so horsepower and considerably more torque out of email tunes an no other modifications. We all should feel quite generous. LS2's get maybe 20 to the ground, TOPS without other modifcations. And that is from a very aggressive tune.
I can't stand it when people so "oh my gawd guyz! They wile E coyote is maxed out from the fakterree!! Downt tewn ur piston thingy!" Nonsense. Better drivability, better idle stability, better throttle response, better F/A ratios, better power deliver, killing skip shift, and adjusting redline. Best money I've spent on my car thus far. How many satisifed customers are out there with tunes? I'm one of them...
