   Hmmmmm, I typically see 20in/hg crusing, Down to 6.5in/hg closed throttle 
   decel. and up to 68in/hg on full boost.  This is all with a Aircraft 
   STC'd Sensitive Manifold pressure gauge.  Meaning that it's spot on.

Just to make sure we're talking the same units:

  decel:   20-25InHg "vacuum" re atmospheric ==~ 5 - 7InHg "absolute";
  cruise:  10InHg "vacuum" re atmospheric ==~ 22InHg "absolute";
  accel:   10PSI "boost" re atmospheric ==~ 54InHg "absolute".

So we're "spot on" with each other, yes?
