Jim,
Yes, it can be used in flight.  True about the MP vs. Airbox, that's why I 
think I may need to fly down to Lockwood.
I was hoping I had a leak in the carbs or MP gauge something akin to that 
but it doesn't seem to have a leakage anywhere, and besides that would drive 
the MP down not up with altitude...
What I am seeing Jim is a steady rise in MP with altitude increase with a 
fixed throttle.  That is weird as the manuals don't seem to indicate that 
should happen except for the high airbox temp cutback.

Regards to Heather,
Bud
