Advice needed
I’m helping a friend of mine out with his truck.
It will randomly shut off and is low on power.
i used my autoenginuity to test the ICP IPR and IPW. Attached is a link to a video of the WOT test. As seen the ICP is very low while the IPW and IPR% are high leading me to believe he needs a new HPOP. I am going to let him try my ICP to see if that’s the issue before buying a HPOP. Any other suggestions, not my truck so I don’t want him to spend money before we truly diagnose it.

Your scale factor on your FIPW is off. You are reading in seconds, when you want milli- or microseconds. The FIPW on the top right shows you running 5.4 ms at WOT, and that sucks ICP down like a big toilet swirl, then the ICP will skyrocket when you let off the throttle all at once. Look at the 2600 ICP with 10% IPR and 0.6 ms of FIPW (off) in the last seconds. You have a hot performance tune in there. Get back to stock or lower the HP tune and watch the results.
As for stalling, CPS might have failed - or that IPR has a loose tinnerman nut, or it's overheating and failing.

I told him to buy a CPS, and we already checked the IPR. I don’t think it’s the typical IPR fails when hot, I had that issue and this doesn’t seem to be a similar case as we tested at 190*+ oil temp

If his o rings were bad wouldn’t he have a oil consumption issue?

Not necessarily. If the top O-Ring is shot, the oil can ooze up under the valve cover, to make an aggressive oil recycle.

Yes he would, depending on which set of O-rings it is.
