What should icp and irp be at?

So truck is a 2004 f250 6.0 with 170000 miles

Oil changed 1000 miles ago with rotella t6
Along with fuel and oil filters (motorcraft)
And new repaired ficm

Truck has been acting up. Won't build boost tell higher Rpm's and black smoke
Before the turbo spools. And the turbo doesn't seems to be acting riight. Also last time I went to start it it reved up real high then after a little bit it settled down. Truck has a rough idle and seems to miss and it runs better right before it gets to full operating temp.

So question is what should my icp and ipr valves be at start up, cold idle, hot idle .
