John,
    If you don't want to believe what Pete or I were trying to tell you then I doubt you will believe the TCM service bulletin either which calls for fuel flows at take-off power to be 41.7 – 43.4 gph.   The GAMI guys recommend more than that.   I'm confused about your comment about landing at a higher airport.  A turbo charged engine doesn't care what altitude the airport is.  30 or 38" of MP is the same at 25000' as it is at sea level, and so is the fuel to air mixture ratio.   The TCM service bulletin is SID97-3D.  Look it up for yourself.

I’m getting 36-38 GPH take off flow on my TSIO-550E.  I was told this is too low but I don’t believe it.  If its higher than 38 it may cause a problem during take off at some higher altitude airports or when changing from LOP during landing….just my opinion.
