Just a thought, but perhaps the problem could be solved by using smaller 
tubing for the MAP sensor input.  As you know, I work the Proprietary Software 
Systems AOA booth at the airshows, and we supply all the required tubing for 
the installation.  The tubing used for that instrument is a high-grade 
urethane with a really small ID.  I don't know exactly what that ID is, but I 
do know that the OD of the tubing is only 1/8".  The reason that small tubes 
work ok is that we are not looking at moving any volume of air through the 
tubes, all we want to do is transmit the pressure seen at one end to the other 
end.  Consequently, a small capillary does that job admirably.  Just a 
thought.
