N75 turbo control map , setpoint for vanes in turbo VNT mechanism, google vnt turbo to get a better picture of it, more closed vanes faster turbo spool faster boost but also higher chance of overboost, more opened vanes slower turbo pressure build up higher chance of underboost. Changes in fuel and boost require changes in this map to keep actual and specified boost inline (to regulate overboost or underboost conditions)
