While the turbo takes care of airport altitude changes, the ambient temp is still a factor.  The difference in required fuel flow between 50 deg F and 150 deg F manifold air temperature is 10%.  Sooo, if the required take-off fuel flow at 50 deg F is 45 gph, then the required fuel flow at 150 deg F is 41.5 gph.  Pushing the "rich" take-off fuel too far will cause a problem on hot days.  Adding the high boost will further the bad cause.  This is just information, I have no opinions what so ever on the accident.

 Colyn,   48-49 gph without high boost. I will check the answer to your second question
when I return but my recollection is about 1-2 gph-- not much.    Jeff

Jeff said, Trial and error but I found it to be around 48-49 gph
 
Jeff, did you mean 48-49 is about the place where the engine begins to
complain or is the place where if you add high boost then it complains. ?   
Do you know how much high boost adds to fuel flow when wide open?    e.g. I
have mine setup for 45gph without boost.
