1 being full vaccum , 11 atmospheric pressure, 14 = 4.3psi or 18.9psi i think

Are you sure that is correct as from 11 effectively 0psi to 14 around 14 psi you do not seem to have any Ignition retard for boost, Is there another table somewhere retarding Igintion, You also seem to have lots of Ignition everywhere, Was the timing the same at the crank or has it been offset.
