John,

Going above 38 gph isn't going to cause a problem. The TSIO-550E in my ES flows at 41 per hour on takeoff. The GAMI folks said to take a conservative route, since fuel cools the engine. Another question is: Did you check and set both fuel pressure levels (idle and WOT) per the Continental spec? If you have had it done, you may want to get it checked again.

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.
