So that wasn't the issue. FML. Sitting in subaru's service department. Dunno what else to tell them. Still only getting 9lbs of boost. HELP
So Subaru mechanic had the pill hose on the wrong side. Had to show him the diagram. Now I'm boostin around 14.9 target is 17. Ran a hwg map provided from Cobb and it produced more than the normal one. Still under boosting by 2 psi. Normal for OTC tune? Checked all my hoses to make sure they were ok. So I don't know what the issue is now. Any help?
Talked to a tuner friend. He thinks I blew the ring lands. He told me to open my oil filler while the car was warm and if it smelled like exhaust fumes that that will prolly be my problem. And it smells like pure gas/ fumes. So I imagine its blown ring lands?
Blown ring lands don't affect manifold pressure, which is what your boost reading should be.
If you suspect engine failure at that point, do a compression test.
I didn't see if you actually checked the TMIC coupler/connection to see if that was tight or not. That's a common source of a boost leak.

Opening the oil filler isn't going to do anything .. if you suspect a cracked piston then you need to do a compression test.
Which coupler should I check. All the connections to the TMIC?

target for 93 OCT stage 1 map is: 16.5psi peak boost pressure tapering down to ~13.5psi by the 7000RPM redline, +/- 1.0psi
depending on what map you're running, your numbers dont seem too off.
