Default Tech Help! - No turbo and P0432

The title asks for Tech's help, but I'd welcome yours as well :-) I have a 2002 S80 T6 - Executive Edition, if it makes a difference. I recently replaced a malfunctioning coil and got rid of a misfire and rough idle. However, I'm noticing a very slight decline in acceleration in 1st - 3rd gears and I have very underwhelming acceleration when I'm in 4th gear (after the torque limiter kicks in). Also, it appears that I have no turbo. I only realized this when I tried to "punch it" while in manual mode (again, in 4th gear). I was originally getting P0432 and P0422 codes, but I used some Mass Air Flow cleaner, put Sea Foam in the crank case and fuel tank, and cleared it. I ran it through the cycle and now I only get the P0432 code (although it drives the same as when I had both codes). What's going on? Could there be one thing that's causing both the hesitation as well as the lack of turbo? Thanks for your help, fellas and gals. Here's my OBDII Freeze Frame reading:

Load: 8.6%
ECT: 183 degrees F
SHRTFT1: -3.9%
LONGFT1: 3.9%
SHRTFT2: -2.3%
LONGFT2: 3.1%
RPM: 1680
Speed: 41 mph

It sounds like you have a big air leak. Check boost hoses from the intercooler or the boost pipes on top of the engine.

One of the turbo hoses got disconnected when I changed the coil. So I put it back and that solved the issue of the turbo. Regarding the issue of slight loss of power, I took it to the mechanic and he changed the exhaust cam solenoid. $223 later, the P0432 code is still there and it drives exactly the same. This really pisses me off, but I guess that's just part of the process of determining a root cause. He said that a vacuum leak would show up on his scanner, so that's not the issue (according to him) and the O2 sensors are fluctuating as they should (according to him). Any ideas? Thanks.
