<<PS:  Does this mean a  3% power increase (61%-->64%, 19.1"-->20.1")
yielded a

Scott,
Something looks suspicious.  Power is going to change with the third
power of velocity.  Your sample data points require about a 22%
reduction in power.  The fuel flow readings seem to agree with this.
What's up with the MP reading??
