That was my way of looking at it,

In a dive your airspeed will go up thus the RAM air pressure will increase so the pressure at P2 (compressor inlet) will increase causing a rise in the EPR, but.......

when the velocity of the air increases, as in a dive, the pressure of the air would drop at P1 thus causing a drop in EPR
