Turbine inlet temperature - Not indicated on turbine engines I work on.
Usually ITT, interstage turbine temperature between compressor turbine and power turbine sections is indicated
EGT is idicated on piston engines as an aid to leaning the mixture, not so much on turbine engines.
In any case will be lower than ITT and TIT.
Pressure out of the compressor is a function of the compressor stages in axial flow and compressor size/effenciency in centrifugal compressor; and is expressed as a ration over inlet pressure.
Which leads us to bleed valves and interstage bleeds to decrease stall margins etc.
