Guy, 

Stuff to check:

a) did you actually get all 6 cylinders to peak and then to the lean side of peak?
b) is your MAP transducer accurate?   I've seen more than one that isn't.
c) is your fuel flow accurate?

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
