TCI 700R4 Trans pressure bouncing around?

I have a TCI 700R4 trans hooked up to a 454 with a mildly modified cam. When I try to do a trans pressure check, the pressures jump around from approximately 140 to 160 psi while in park. When I put it in gear, it will drop to about 120, hold steady for a moment then start bouncing around again.
Would this be normal due to the modified cam? Im trying to adjust the TV cable and the directions say to move the slider until the pressure changes by 2 to 4 psi and thats hard to do when the pressure is bouncing around.
Any input would be greatly appreciated.
