I'm starting to fiddle around with my 2020 Mustang GT and I'm curious if I should be concerned about the erratic behavior of my cam phaser (specifically on the intake cam). I dyno'd the about a month after I picked it up (406hp/379tq) on whatever gas the dealer filled it up with. I logged the dyno run - see here:

In the graphic and log from above, you can see the cams very closely and very precisely were able to follow the commanded angles. Now in the pull I made this afternoon (granted it is in 2nd gear) you can see the intake cam specifically seems to struggle. Is this indicative of a failing phaser or some other issue? Log -

I'll throw up my tune that is currently in the car:
Mig v2.21.hpt
Drop-in Filter and a Corsa cat-back is all that is fitted to the car engine wise. Car has 2300mi and had the factory fill oil changed to Pennzoil Platinum 5w-20 @ 1000mi.
