200 20V Running issues/ Code

Ok guys, I've run across a stumper.
I'm working on a friends 200 20V Avant. He bought it with a running
problem, namely whenever on boost it would start to miss/buck. He had
a friend of his pull the line off the wastegate, and it was "good" for
about a month. Now, it runs pretty poorly all the time, to the point
of dying on occasion.
So, I checked the cam timing, spot on. Checked for boost leaks, can't
find any. The code that comes up is 2224. Here is the description,
courtesy of SJM autotechnic: "Maximum Charge Pressure Exceeded,
Intake air leak after turbocharger, ECU Vacuum/pressure line has leak
between intake manifold
Waste gate or pressure hose, Waste Gate Solenoid/hose problem, ECU
pressure sensor malfunction
Symptom: Misfire during wide open throttle, boost pressure too high"
The symptom is exactly what I'm experiencing. I pulled the line going
to the ECU, and I have good vacuum and boost present there. What are
the chances of the internal boost sensor in the ECU going bad? Anybody
have any other ideas?
Stumped in Oklahoma,
