Default Saab 92X Aero not making power - Cobb AP v2

Hi - I have a 2005 Saab 92x Aero with an AP v2 that made 235hp at the wheels when I got it, but now seems to make a good 25% less, but runs fine overall. Here's what it has:
  • Custom dyno tune for the AP done by Agile Auto
  • Originally dynoed at just under that what a stock STi does on the same dyno. It's a very safe map, reliability/longevity was primary to making power.
  • Cobb Accessport v2
  • Turbo XS stealthback exhaust system (basically a full 3" turbo back exhaust that tapers to 2.5" at the axleback). Includes a highflow cat
  • STi axleback
  • Helix up-pipe
  • Perrin panel filter
  • Prodrive boost control solenoid
  • Snorkus removed and replaced with OEM elbow

Here's a log from a 3rd gear pull:

At first I thought it had a boost leak, but I'm not sure.

Any thoughts?

Thanks,

Alex
