I don't see any reason to run the engine outside the Manufacturer representation for best power or best economy and in agreement with GAMI recommendations. =20 =20 I run my TSIO550 full rich on climb and then lean back to get the TIT less than 1600F ( 870C). That is often 150F (85C) degrees LoP EGT. =20 Robert M. Simon ES-P N301ES
