I have one also. I am running a TSIO550-EXP with one Lightspeed Plasma III and one mag. For a year I would climb to cruise altitude, pull back to 32 inches and 2450 rpm, lean to 17.3 gph, and go merrily on my way. EGTs were 1550-ish, TITs were 1580-1620, and CHT varied with the season (390 in the summer and 350 in cooler times). However about 4 months ago my EGTs began to increase and with them the TITs. Now to keep TIT below 1625 I must lean back to 16.3 - 16.5 gph, and that yields a slower TAS. =20 Anyone suggest a cause and cure? Robert M. Simon ES-P N301ES
