Greetings! So yes, since I installed the new engine Monitor, I get 10 GPH at 65% power, at 2200 RPM. It seems that at lower RPM, the tit is lower. I keep my tit at 1700 or below, and 65% normally gives me 1650-1675. Other owners use more fuel to keep the TIT even lower. Some say they run their turbos in the 1600's, which of course is going to increase the fuel flow. My turbo was Nitrated by Western skyways, and they said they have great success with this procedure, and told me not to worry about the tit temps with the nitrating process, but they couldn't tell me to run it above the Manufactures limits, for obvious reasons. Rockwell has a max of 1725 for the TIT, but says "for longer turbo life, run the turbo at 1700 or below". At 65%power, I flight plan for 138 knots at 12000 feet. at 75%power, I burn 13 gallons per hour and get 148 knots...BTW, the new engine monitor was much more accurate so I'm able to fine turn the engine...the old monitor wasn't telling me the truth, and reported much higher TIT's...Also note, the TO-360 is a carbonated engine and cannot be run LOP. Any other questions, give me a call at 618-558-7897... Also note that my mission has changed, so I just sold the Commander and bought a Columbia 400.... I'd say the commander vs a Columbia is like a 707 vs the Concorde... As much as I like the speed and range of the Columbia, I miss the Looks and Room of the Commander
