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.

Subject: [LML] Why is my fuel burn so high in my IV ????

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
