I'll let you know how hard the job is to do in my driveway. It's pretty straight forward. If the phasers are shot, they're $150/ea x4 + single use bolts.

Sorry for the shitty pics... Tackled the chain yesterday. It ended up being 1 tooth out of phase. It had enough slack for me to almost skip another tooth by hand.

Also, it seems to build boost now. So, being a tooth off might have caused increased intake pressure and the PCM wouldn't command boost at that point. Putting miles on it to verify that was the root cause

I bought the truck new with 50 miles on it 5years ago. I don't baby it but I don't beat on it. I change the oil regularly and have never had an issue until this point.
Look at the video link, I had zero abnormal noises while running (hot or cold).
yes, being 1 tooth out will do what you described also. I had mine about 14 degrees retarded after I changed the belt. Car would run ok, and made boost, but was blowing it all out the exhaust valve. Manifold was a nice glow...
I decided to check timing and found out it was so retarded, twist the distributor up a bit and put it at the base number, it runs like a champ now.
So yeah, basically the same issue you were having with similar results. I just don't have any limp mode or OBD.

It's weird because it didn't really ever go into limp-in mode. It would still advance spark 10-40 degrees, let me WOT (which is probably where I skipped a tooth during low boost diag). It just seemed to command the turbos to vent and not keep the boost in the intake.

New question for you. His timing chain, spark plugs and coils were all changed. Now we are on the way home from work and anything over 1/4 to 1/2 throttle at any speed the truck start shaking violently. Not throwing any codes. We are cruising at 75mph right now on M59 and its smooth. Soon as he gives it gas to accelerate and pass it starts shuddering and shaking. Any ideas? It's a 2012 f150 EcoBoost.

Condensation in the intercooler was an issue on those. They had a TSB to block part of the intercooler. Also, some people drill a weep hole in the CAC tube to drain moisture.
Does it have a check engine MIL illuminated?

No lights or anything came on the dash. We drove from the Palace in Auburn Hills to 16 mile and van dyke. It did it the entire way anytime he gave it 1/4 to 1/2 throttle. Moisture in the intercooler can cause this? It literally started doing it right after we pulled out of the parking lot. We figured maybe when it warmed up it would stop. But 23 miles later it's still doing it

Well. We just drove it into work this morning and it's doing the same thing. Except now it has a check engine light that stays on. Right before work a few miles the check engine light started flashing and stayed flashing. Hes had to replace coil packs on this thing 3 times I guess. Idk if some of them are already dead again. Only about 5,000 miles on current ones.

Stop by AutoZone and ask for them to scan it for DTCs.

It sounds like condensation is building up in the plug/coil holes and getting past the boots. This might sound a little like some redneck engineering, and it is.. but try coating the coil boots with WD40 before installing them.
