 You need to use a very good set of pressure guages with small
 incrementation.  Set the low side pressure to the 7-9 psi, then the high
 side at full throttle to 45-46 gph.  Recheck the low side to assure it has
 not gone outside of parameter and your done.  It's very difficult to do a
 full throttle run up so I elected to make an adjustment and then a high
 speed taxi to define the fuel flow at takeoff power.  It only took two
 iterations to get it real close.
