The solution to your issue is to identify what changed. Elegantly simple but frustratingly difficult to execute.
Learn about the timing chain replacement process. What sensors are removed, unhooked, etc... What components are removed, and in what order.
Then you need to create a checklist of every part touched, and how it could affect the situation you are experiencing.
Don't jump to conclusions, because that's how a person hits a dead end when trying to solve a service issue like this. Because you observed the change after the timing chain replacement, you assume it happened as a result of the dealer. But you don't have any verifiable evidence, you have symptoms that began at a specific time.
You DO have a second dealership that confirmed correct timing. So now you need to step one level higher and ask Ford to help list out everything that can create the symptoms you are experiencing. The forum is also spitting out a lot of potential causes.
Is there a high probability that something happened while at the first dealer? Yes, but I have literally had a check engine light come on while leaving the dealer, that turned out to be a new and unique problem.
Good luck, I know exactly how it feels to be in a long term troubleshooting nightmare!

This is why I paid for a premium extended warranty through the dealership I bought it from. It's their job to check all this, the problem happened immediately after they performed their work. Keep in mind my Turbos also didn't work after they performed their work, I had to take it back and get them to fix that thinking that was the whole problem but it wasn't.
The second dealer went through everything and when he started to question Ford about the Fuel to Air ratio and it possibly running rich they told him it was normal and refused to send an Engineer who is an expert at diagnosing problems on that engine. Where have you ever heard of a situation where you couldn't escalate to have a problem solved? My wife already refuses to buy a Ford due to their crappy customer service and might soon be joining her.

BBB Autoline. They will get an engineer out there for your issues. The engineer will most likely not solve anything (speaking from experience) but they will at least get someone out there. My truck is going in AGAIN Monday for timing chain noises, trans issues with 1-2, 2-1 shifting, drivers seat heater inop, peeling wheels, peeling grille, smoke on start up, and gear whine from the rear end again. I have had an engineer out to look at my truck, blamed the condensation in the intercooler on my AFE cold air intake and gear whine on my tires. 54k miles on my truck too. I wont have it once the extended warranty runs up at 75k

Do you happen to know what peak boost was in your dyno?
Your PCM, etc is seeing load demand and providing the fuel to meet that demand but it sounds like your boost isn't there to compensate. I would check sensors and ALL turbo piping first. Could be something as simple as that.

On full acceleration I hit 16 psi of boost. Again the Hub City dealer I assumed checked all that, they had it and worked on it for 3 full days and were focused on the fuel delivery system.

I will work on the BBB Autoline process starting on Monday. Going to the hunting camp this weekend where we have no computers or cell service, going to enjoy the stress relief, I need it.

13.5:1 to 15.5:1 air fuel would be considered stoich, and very lean under WOT. You would surely damage the engine running like this.
I'm not trying to argue with you, but you are very incorrect.

10:1 is not lean, that is dead rich. Stoich for E10 gas is 14.07. Under WOT with a boosted application you will want to be from 11.0-11.8 in most cases.

Sorry you're right I had it backwards. I'm guessing the Torque pro formula I am using is not very accurate then.
