Speed increases  to the cube of the power increase.  So, to get a 2% increase in speed, you need a 6% increase in power.   To go from 195 knots to 213 knots (9%) will require a 29% increase in power.   That's not trivial.

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??
