Guy,

You didn’t say what you EGTs are, but it appears to = me you are on the rich side of the power curve. The lower fuel flows are lean = of peak.

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,
Guy Foreman
