The cycling is really annoying and rpms jump everytime. I'm guessing the switch is bad. Does this look like the right part: "6 Cyl Switch, Pressure 96-00 F5VY-19E561-A" Black E0 SVT

Low side pressure goes up with ambient temperature to 45 Psi or so on a 90 degree plus day. If cutout is above 25 Psi and your gage is accurate go ahead and replace the switch (or adjust it, many CCP switches are adjustable), otherwise I think you are just a bit low on R134-a.
