losing boost under load Please help

I have a 2000 f-250 7.3 has edge evolution box, mbrp exhaust and s&b cold air kit. I have noticed here lately that when under a load the truck is losing boost. I know when I first got the truck it would make 18 to 20#'s of boost before it would lose it out the waste gate. Here lately It makes 8 to 10#'s then it dumps the gate. makes a shshshshshshsh sound until you let off the pedal. Does anyone have any ideas why the truck is doing this? Any and all help will be greatly appreciated!!!!

It might be sucking the boots off your intake or CAC somewhere. Check the booties on the CAC and intake to make sure they arent super caked with oil, clean them up if so and try again.
