HPOP question.
I'm checking the health of my HPOP and need to know what the - ICP PSI, ICP DC% numbers should be.
I have a Stock HPOP, tested in stock tune, and Oil temp was 165*
I took a 5 mile run at 60 MPH with the RPMS @ 1,730
ICP PSI ranged from - 985 to 1089
ICP DC% ranged from - 19.8 to 21.4
Can you tell by those number the condition of my HPOP.

To really find out you need to run it kinda like on a dyno, from the bottom of say 3rd gear. This will tell you how it is doing. For example mine drops to about 1800 psi and in the 88%-92% DC. If you need help give me a call.

Do you want the easy, quick version or the drawn out one? The long explanation is click here
The quick version is get out and cruise at highway speed, then hold it at WOT from around 55 mph up to 90+. (using the data logging option so you can watch the road of course)
When you get back, watch the ICP to see where it peaked out at, then watch where it fell off to and see what pressure it could maintain.
