With all the recent posts about boost pump operations with respect to Lancair IV's and the TSIO-550, I am wondering if there is any consensus as to what the correct procedure is with a Legacy and a normally aspirated IO-550?

 

I have just under 300 hours on my Legacy and routinely fly in the mid-teens and as high as FL210, never having a problem without using low boost.  (Except for takeoff and landing)

 

Any other experiences counter to this?

 

Thanks,
