Reading some of the posts on the LML about IV/IVP drivers. Just wondering how they are getting around 18-19 GPH at cruze power? I have a straight IV with a TSIO-550-B. I usually fly around 10K feet, using 28in MAP, 2400 RPM, Leaning to 1550 TIT, and getting 21.5 GPH fuel burn. What am I doing wrong? How is everyone else getting there fuel flow so much lower?
