All the direct injectors flow the same except #3 (The one with the heaviest heat signs in the injector body). This one flows 14% more fuel before and after cleanup.
I will check #3 cylinder thoroughly with a boroscope and test % leak down and compression when I put it back together. The spark plug looked a little leaner than the other three but not so bad so I think the cylinder is fine.
As I mentioned in earlier thread, I noticed the high pressure rail hold down bolt for #4 was not the same thread or head size than the other three. These bolts are M8x1.25 thread with a 12 mm head. These butchers went to a 3/8" - 16 with a 13 mm head and called it a day.
I did call Subaru and documented everything thoroughly to them on the phone and in writing. This is not cool at all and I need a regional service manager to look into this and get me some answers.

I recommend just completely replacing the injectors. They get damaged with the heat they see when the seals go bad.
