Good stuff here.
If I may, I would also suggest the next time you run a datalog to look at your VCT operation to see if it is showing slow response especially down low below 2,500 RPM (too large a gap in time between VCT commanded angle vs VCT actual angle....should be almost on top of each other & in synch when operating properly) as these 3V's oil pressure spec is 75 psi @ 2,000 RPM when all is new so unless you have a mechanical OP gauge installed to know what the actual operational OP is below 2,500 RPM's you'd be making assumptions but by logging the VCT PID's they'll give you some insight into this.
I say this due to seeing your WOT TQ curve line from 2,000 to 2,500 is almost flat before the TQ curve starts moving upwards looking like the VCT may be a little slow to respond to PCM command until oil pressure comes up some (takes more oil pressure\volume to retard the cams quickly due to overcoming the cam phaser's wound spring tension in addition to the valve spring tension applied to the cam lobes thru the cam followers\lash adjusters & according to Ford they recommend the Hot Rod cams to be around 7* retard for max WOT low end HP\TQ output from 500 RPM's thru 3,000 RPM's....why Dino is suggesting looking at the WOT cam retard timing settings in tune) but the causes as to why VCT response is slowed are many so I suggest to log the VCT PID's (or install a mechanical OP gauge to read actual low RPM OP) to confirm this before chasing this rabbit.
Been here, done it is why I'm suggesting this & it don't take much oil pressure\volume loss in the VCT system to hurt low end HP\TQ output below 4,000 RPM's on these 3V's.....especially if your engine has high mileage.
Just a suggestion..................................
