 MessageBryan,
 I also have a TSIO 550E from Barett Perf.
 The fuel flow at full power (38.5" @ 2700 RPM, full rich of course) should be
set at whatever is necessary to keep the TIT's at 1300 degrees or less.  This
will provide plenty of margin that your internal cyclinder pressures on
take-off do not get to high.
 It will probaly be at least 44 GPH.
