not sure honestly..... those tunes are pretty well sorted out but every truck is different. Check the basic stuff first like oil in the ICP sensor connector etc.

Your ICP seems high. My truck idles very choppy at 750 psi, and idles much smoother at 500 psi or so. This is with 100% nozzles though...

What could cause such high ICP? a faulty IPR not letting enough oil bypass? my UVCH's are the originals that were on the truck, and the cam position sensor is the recall unit from 03ish, I had a new CPS I got from ford (where I work) but that one failed so I installed the old one that I had replaced just because I got a free CPS. Thanks for the input with this everyone.

Could be a faulty IPR or a Faulty ICP sensor. Unplug it and see if anything changes.

It has a very little hiccup, but nothing changes when I unplug the ICP sensor.

If nothing changes when you unplug the ICP sensor, it is bad.

I replaced the ICP sensor with an old sensor that I had the same scenario for replacement the CPS, nothing changed, wasn't able to do anything else
This weekend but hopefully soon.
