No CEL, NO Boost, No performance

So a week ago I thought the transmission just wasn't shifting correctly. Looks like instead I've just go no boost and the car is in such a lack of power that I can't safely drive it.

2003 9-5 Aero Automatic

Since I'm not getting a CEL, nor am I getting any Freeze Frame data from the Tech II here's what I've tried:

• Replaced Throttle Body with a new one (needed this anyway)
• Tried two other throttle bodies since the new one didn't make a change to this issue
• Verified none of the throttle bodies are going into Limp Home Mode
• New Air Filter
• Removed Cobra pipe from the turbo and made sure the impeller was not seized
• Removed the Wastegate line from the Boost Control Valve and ensure it worked and had not fallen off (using air compressor)
• Swapped Mass Air Flow Sensor (two different ones known good from another car)
• Swapped Charge Air Pressure Sensor (known good from another car)
• Swapped DIC (with two known good ones)
• Swapped Intake Pressure Sensor (with known good one)
• Swapped Purge Valve
• Swapped Bypass Valve solenoid
• Swapped my Forge Motorsport's Bypass Valve with a known good Bosch
• Swapped Boost Control Valve (twice with known good ones)
• Replaced all vaccuum lines
• Replace Plugs (known good and a brand new set)
• Checked Catalyst (Catalytic Converter) function with Tech II
• Pressure tested turbo charger system (blocked hose from turbo and again at throttle body as per WIS. No leaks in lines, induction or intercooler

Essentially nothing has made a change at all... Reset the ECU after each swap and test drive. The boost gauge sticks right at the junction of yellow>green and only moves down just slightly for a brief second when I let off the accelerator. The performance is so bad that it won't even build up enough power to move to the next gear. I can (barely) get it to highway speeds if I use the paddle shifters to get going.

Any ideas?
