txs to george and charlie for the answers. I forgot
the add the engine setup, I had the engine set at 2450
rpm and 31.5 inches of manifold pressure, I had leaned
the engine as per George's preaching and it has ran
smoothly with TIT2 (the hottest one) at 1640 which
translates in my engine to 15.9 GPH more or less. I
did notice a bit of roughness thru the flight from
Taos NM to Mesquite but nothing different in engine
performance. Will look at the turbine blades in am
when I remove the bottom of the cowling. Appreciate
all responses, I have an E model 550.
