Climbing at or above 120 - 140 KIAS is preferable, particularly when
climbing to higher altitudes, i.e., those that require more than 6000 feet
of altitude change. A 500 FPM rate climb at cruise power provides
better forward visibility and engine cooling. The engine should not be
leaned during climb.

Above 20,000 ft., maintain a minimum of 2500
RPM to maintain turbocharger speeds for cabin

LEAN OF PEAK ENGINE OPERATION
The TSIO-550E engine can be operated lean of peak at power settings
of 65% and below. Starting from full rich, the power increases about
1% as “Best Power” mixture is reached. For cruise operation, best
power is at or near 1625ºF TIT rich of peak. If the mixture is leaned
further past peak TIT, the power drops 8-12%. “Best Economy” is
reached at about 50ºF lean of peak. Because of the drop in power,
speed will be reduced. Once a lean of peak mixture setting is reached,
the RPM and manifold pressure can be increased carefully. By
increasing the manifold pressure while operating lean of peak, the
power loss from leaning can be compensated. For continuous
