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 ------=_NextPart_000_0215_01CDB95B.5DB4B9A0 Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable

LOP is the short answer.  TIT in the 1450 range – about 16 = – 17 gph.  Give up a little HP and speed maybe five knots or = so.
