I think the a/f sensor when reading rich and not switching to lean,is trying to compensate for an air leak.I too believe its a intake or pvc leak,as long as your 100%sure timing is correct.

Question for the builder:
Did you get both cam phasers and crank marks to line up or just one banks cam phaser to crank gear?
The timing marks on each chain and vct never matched. I could only get either the left or right bank lined up with the vct and the timing gear sprocket at a given time. I marked the bank that did not line up using white out. You can then remove the chain guides and tensioner. I did not have to rotate the crank to release tension on the chains. Once the chain guides and tensioner are removed, you can rotate the chain around the sprocket. Once the chain is removed you can slide the timing gear off the crank with little to no effort.
When installing the new crank gear, are you certain you moved the timing marks over to the new gear correctly (marks made on stock gear matched new gear?)
Did you mark the chain on the cam phaser that was not lining up with the marks on the crank gear indent? ( I noticed that I could only get one side lined up at any given time ).
Engine was not 180 out? (I doubt it was....it runs)
I put my chains on using my own timing marks on the phaser that did not line up (blue key to indent) This means you would have to install the chain using those marks not the factory marks on the chain.
Did the crank pos learning values get reset?
Moving on...
Has the passenger side PCV assembly been checked for accuracy? The one way valve is installed the correct orientation? ( In all honesty, I doubt the issue is related to the pcv system...more accurately, the hose assembly but a vacuum leak could effect your FTs.
Intake manifold doesnt need removal for this install so that should not have any leaks lest it was removed.
Rule out:
Plugs/Gap (swapped coil packs yet?)
Lets assume mechanical timing is accurate but again I've seen a similar issue on another install and timing was the issue in that instance
Vac leaks (do you have a smoke machine?)

Well guys finally got the car back this weekend. Car runs fantastic
Problem had nothing to do with jumping a tooth. Turned out to be a bad o ring on the pcv system and a bad gasket for my cat deletes. Boosting around 11lbs now shifting around 7500-7700 but was told by Lund to shift around 7200rpm.

Is there any chance you have the data log from this?
I'm having the same issue and my VVT Exhaust logs show that they do not match up as other peoples do. I'm wondering if yours was the same way and that I might have a gasket issue rather than a timing issue. I'm not looking forward to opening the engine back up to correct the timing if it's not an issue. I'm not throwing any timing check engine codes or any CEL at all. Kinda confused about it.
