Here's a log from a Member on this site. Factory stock 2012 GT on the stock tune.
This is a 5th gear run and it shows the ECU commanding a lean A/F at WOT, then cat overtemp protection kicks in and richens the mixture. You can see the ECU is also pulling spark (likely thru Knock sensors) in an effort to save the motor.
Imagine if this was a tuned car with off-road exhaust. A tuner may turn off Cat enrichment since there are no cats, add some ignition timing and if it was a year ago, modify the knock sensors to not pull as much timing.....
Tuners made the problem worse, but they did not cause it.

to the people that allready have the cammed tune, when you rev the motor up (on that cammed tune) and let off the gas so the car can go back to idle, is there that popping sound from the added fuel that I keep hearing on other cammed tunes when there are no CATS on the car??
Well i gave the tune a run for its money this morning. Started witht he cam tune this morning but had to pull over and throw the performance only tune on due to a minor stall issue which Shaun will kill with no issues. Other then that i putted around and brought the car up to 4K pulls and then the highway came, i took a deep breathe, grabbed my crotch and told the car "dont fail me now slut" and then it happened, i revved up and let her rip and all i have to say it HOLYYYYYYYY SHITTTTTTT i swear i gained 50lbs of TQ and the car wouldnt stop pulling up top 
i watched head after head turn as i blew past them all as if they were standing still and they had to have been going 80 minimum. I can say this that i def have a mid/low 11 sec car with a tire as she stands. Any doubters, **** you... Shaun you knocked this son of a gun out of the park. Hell i think this car can easily pull on a modded cobra now cuz i barely lost to one with my old tune, with shaun's tune i know i can walk away this time

I'll have to double check on this. I wanna say no, but I don't recall for sure. The only time I recall getting the popping is if I'm engine/compression braking.
Glad to hear you're happy with your tune. And I feel the same way. This thing isn't barely stronger than my previous tune, it blows it away. And I agree...the more throttle you give it, the stronger it feels.
I loaded a new revision this morning and then drove it to work in rush hour traffic. No real chance to wind it up hard, but it does feel as if Shaun worked on the low end and the throttle response. It seemed very eager to move out. Every tune I have had from Shaun has been great, and they keep improving.

U guys r really making me wanna get a new tune. I'd really like to hear from some people that have his tune on an auto, though.

Shaun, that is an exceptional and informative post. I don't want to hijack this thread, so maybe you could start a different thread because I think this particular topic requires more attention.
I don't spend my entire life on forums, so maybe I missed other similar posts, but this is the first explanation that I've read that even seems plausible. Why is this information just coming to light? To me, it would seem like it was in the best interest of the "tuning vendor community" to make this information as widely known as possible in the clearest possible terms. Up until now, it's all seemed very hush-hush. That's only hurting vendors.
Regarding alleged stock cars that have experienced this issue: I've seen many people claim stock cars popping, but I've yet to see any actual evidence. Is there anything further you can share here?
I REALLY REALLY want an AED E85 tune, I have read some bad things (havent we all though) however, Shaun seems to put more on the table then ANY of the tuners I have dealt with over the past 2yrs w/ my 2011. My car is suppose to get dyno tuned this weekend, and Im half tempted to bail out of that and have Shaun do my car w/ email tunes, just because of everything (90% good) I have read. However all this #8 crap makes me leary of changing tuners when I know something currently works well. But I think it could work better with Shauns tune. I looked at my computer code lastnight to make sure it wasn't the same as the problem cars (my car was built June of 2010), I am going to go home tonight and do a compression test on my #8 and probably go from there. The car has run great for over 28k miles so far being modded etc. But after everything I have read, I have to admit I am curious.
All I can say is call Shaun or email him. He takes the time to explain alot of stuff to you and I was more than comfortable after talking to him via Email. he took the time to answer every question i have asked (even the dumb ones lol) I have full confidence in his tuning abilities and have no concerns about my motor on his tunes.
your telling me, i spent a good week of his time picking his brain at every thought i had. Shaun is like no other as a tuner His work backs his knowledge 110%, RSKtakR good luck with your compression test, we have similar dated cars. There is some stuff i found out that makes me a bit happier i picked the 11 instead of waiting for the 12 but im keeping that one to myself
also if you have a 6 speed and know how to shift, i didnt miss not one single power shift this morning. Looks like ill be in need of tires sooner then i thought

Shaun, do you tune for higher altitudes as well? This is something I always seem to run in to with tuning. The car operates okay where I live (4500 feet), but if I drive to the mountains, it runs like piss.
I've been researching tunes, tuners and this just doesn't seem to be common, as most people are at or near sea level.

well I dont have any signs of low compression or a bad #8.. no smoke of any kind, no oil loss or power loss that I know of, I just figured I would do it for the hell of it.
No shop has posted their #8 tune solution. Just like no one posts what they change to make power in their tunes.
I've wanted to post the actual cause for some time but have been requested by other tuners to keep it quiet. I have told a handful of customer tuner buddies what I've found to be the cause. I've also posted hard data on the SCT forums, as well as contacted Ford Racing on the issue. I won't post the actual tune changes...I might as well send my tunes to every shop at that point. The data I've posted on various forums is more than enough for the tuning community (coupled with their own experience and data) to find their own solutions.
However, I do want it to be known that the #8 problem is in the Factory Tune.
As tuners, we can make it worse, or calibrate out the offending tables. It's up to each tuner on how to approach the problem.

What do you mean by running like piss?
Air/fuel is wideband feedback and the Maff compensates for the lack of air density.
TiVCT doesn't have BP modifiers, so cam timing stays the same.
Throtle and spark do have BP modifiers....but they should be pretty good from Ford.
Granted I've never had a 2011+ tuned, but my previous 08 I had issues with tunes when altitude came in to play.
By piss I mean having zero power. To the point that the vehicle could barely move it's own weight. Ultimately to solve that issue I went with a different tune, ditched the charge motion plates and added a 4.10 ring and pinion. After that it ran as it should at high altitude. You're always going to have some loss in power up here, but the car should still function correctly.
It seems as though the changes made to the computer and sensor read-outs in the new cars this may be a non-issue at this point.
