Ae hpop health check on e99

Just did the hpop health check on my e99 per the instructions on woodnthings site. Here's the link, https://b7445ba3-a-62cb3a1a-s-sites....edirects=0&d=1
And here's a link to the video I shot while doing it, YouTube
Just got the ae yesterday so still learning but it seems like I may have a weak hpop?
Any of you ae gurus got some input for me?

run it in "stock" mode, to get your starting reference. But from what i've read, the best place, is the WOT from 60-90mph. Doing it in 'N' gives nothing.

That is correct. You need to be under a load when testing it. Revving it up in park or neutral will not show you what you want to see.

Ya I'm an idiot! Just realized I read all the test wrong as far as testing while driving. So what should an e99 hpop produce pressure wise high and low? Also does the hpx from riff raff have any benefits? Does it help with pressure to cylinder #8 ?

S I just did a quick test, at idle my pressure is between 450 and 480, duty cycle between 11 and 12%. At full throttle in stock program between 60 and 80mph, I'm getting around 2400 psi and 24-25 on duty cycle. Are these good numbers?
Just curious so I ran it on the race program and couldn't develop above 1800 psi in pressure, with ts 6 position chip and their canned tunes on the 140 race setting. Shouldn't I be making more pressure or at least the same on the program as without?

At 2400psi WOT usually your IPR duty cycle will be a little higher. You should be making 2800+ psi with duty cycle at 40% or lower. Since your duty cycle is only 24-25%, this means your PCM is not calling for more high pressure oil. Are you sure you were at WOT in OD?

With a tune(especially a hot one), you will see lower ICP and higher IPR %. 1800psi is low. What was duty cycle like on the tune?
