What is Better : to Plumb Back the BOV or Vent to Atmosphere

Since the CB turbo engines use a Manifold Absolute Pressure (MAP) sensor instead of a Mass Air Flow (MAF) meter
it is possible to use a BOV that vents straight to the atmosphere. Just be
warned, if you do go the atmospheric route, never (and i mean never) drive near
Marc or his house, as you will be risking life and limb.

But more seriously, my own theory on the matter is; since the air has been compressed
and heat given off either by an intercooler or radiation & conduction why waste it?
