I figured it would be a good idea to post up any logs we might have.  Thankfully I have a friend with access to good obd readers that can read info in regards to the turbo. 

Attached is a log from a F550 with TPS from 0-100% along with Boost, drive, load, Speed, turbo speed, and % closed on the vanes.

very interesting that they never allow the turbo to go above 100,000.

I don't know if that's an accident or not.. they also don't allow the drive pressure to go above 100 in hg, or 50 PSI right at that point too.. Wish they put engine RPM on that log though!

It should be there.  It was when I was filtering the columns.

I'll look tom

As for drive I rarely see above 45 psi drive.  It stays really close to 1:1 after 20 psi boost.

OK.. still have some bugs to work out of the logging system.. but here's a log, 2 samples per second of about 20 different parameters.. Need Microsoft Excel 2003 or later to view

The acronyms are

MAP = intake manifold pressure
COT = Compressor outlet temperature (not calibrated too well yet)
TPS = throttle position sensor
RPM = Engine speed
TSS = turbine speed
BPS = front brake pressure
Baro = barometric pressure
CIP = compressor inlet pressure (after air filter)
AUX = dash potentiometer
