They found it was the DI seals and replaced both. 2500 miles after the seal replacements and no issues.
These are allegedly stronger seals:

Yeah thanks, I've already been through all of this a couple times.
I've had all of my seals replaced twice on my own dime.
Last time around they held with the addition of a new tune and oil cooler.
Coils seem to be my only problem now - burning through about one a year.
