alright i just got doing a little modding to the pump, (2 turns on screw) and for some reason i went from having 17 lbs of boost at 1100 F (1/2 turns of screw )before tinkering, to barely 15lbs of boost at 1050 F (maybe) (2 turns of screw) afterwards. and yes i turned the screw clockwise and thats all i did. can someone explain this?

Check the air line from the head to the afc, you might have broke it or left it loose while messing with the fuel screw.
