All the CAI/Tune talk about #8 has left me in a pickle!

Right. Brenspeed cooked some motors too and wouldn't stand behind them. 
Couple of threads here about that.
Bama was the only one I know of that developed a 'warranty'.
The 11's & 12's were the years with the issue. Ford redesigned the pistons for '13. Coatings, different oil control, squirter delete (not needed after redesign).

I Installed my Steeda 93 tune and their cai at 1000 miles. I now have 20,000 without a hiccup. I beat the crap out ot the car the first 1000 to be certain there were no issues before the tune. I talked to Gus at length about the #8 enigma before my install. In short, the aftermarket tunes are even safer than the factory tune (once the tuners figured all of this out). This conversation with Gus was over 2 years ago but I remember him saying that his tune was a bit rich on #8 to actually aid in cooling along with other jargon that I don't remember. Of course more power can be tweaked leaning the car but they tune for power and safety. I will say the steeda 93 tune and cai turned my car into a beast and is very abrupt in the 6r80 tranny. There are some issues with steeda auto tunes about traction and shifting but this isn't what the thread is about. Steeda has 0 #8 failures in the coyote. I will say that i plan on getting another tune from a reputable tuner that specializes in autos. However, don't take this as a bash on Steeda . They are a manual car oriented company and their tunes are insane; there's just tuners out there now that have in house cars that are autos. Steeda's test cars are manuals. Let me say this, if I owned a manual car, Steeda would be my top pick by far. Tune your car!

If you remember, Ford even bragged about how fast they developed the new 5.0. Apparently rushed it a bit too much.

I understand your feelings. But in retrospect, the 11/12's weren't ready for prime time - neither the transmission or pistons. If it was just a 'few', then why did Ford initiate a redesign for both issues for 13 forward?

Thats agreeable. I'm not sure what each specific tuner is doing. But, I am sure they have all veered away from the SCT base tune 
Thats why there was soo much issue in the beginning, everyone was loading the base SCT cal, and making small adjustments, then shipping it with timing tables in place.

Call me crazy but i actually have gotten use to the stock shifter and bracket. I rarely miss the 2nd to 3rd shift even at redline. I find if you don't over think it make sure the clutch it totally pressed to the floor and just go straight up from 2nd youll hit 3rd 90% of the time. Just my 2 cents.

Most people that have issues from an aftermarket tune with an engine and/or trans (MT82) do not post about it online in hopes that the Ford reps that frequent these websites do not catch wind of it, in hopes that the repairs will "slip through under warranty".
