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?
 
Any advice would be much appreciated.
 
Thanks,
