Take a video of it idling warmed up. Unscrew the oil filler cap and see if it stays on top or jumps out. Then take the cap off. Also that filter might be restrictive, try the test with the filter removed and see if there's a difference. Too much pressure will make oil leak out the turbo seals.

Also check your intercooler to see if it's full of oil. It's fine to have some but a huge amount could cause restriction and could have been left over from the old turbo i if it was bad causing issues now.

Final possible issue is the valve cover gasket which has the small intake runners going through it. Under boost it will leak pressure into the crankcase causing consumption through the turbo seals.
