If your atmospheric pressure is only 12.6 psi (as posted in your other thread), then 15 psi boost is darn good.
That pump may be tired a little, but if its building the pressure that's called for, shouldn't it be ok. It's not like he's telling us that it can't keep up.

The second pictures duty cycle says 53.13 % duty cycle, at 3117 RPMS at 3013 psi and 4ms pulse width. Haha my duty cycle is even higher then I thought in extreme. Im also getting oil in my valley, and its not coming from my turbo. Ill try to narrow the oil leak down, its either coming from my plenum intake boots, or its coming from my hpop. I cant really tell at the moment.

Can you log and graph just one WOT run, and set the sampling rate as high as possible so we can see how fast your ICP comes up?
It looks like your DC% jumps way up to get the ICP up and then it goes down some. That's good. If the DC% stayed up or went even higher that would be a big red flag for me.
Like we said earlier. Either your pump is getting tired or you've got a leak somewhere.

I've had the T500 up to 90% DC towing in my hot tune up a big hill. Switched to the adrenaline and it's not much better. I finally just put it down to the 100 tune. Still has plenty of power, and at least is avoiding that flippin' 1211 code.
Someday I'm gonna put duals on. I know everyone says you shouldn't need them with stage ones, but not everyone tows 17k up a hill @ 40psi of boost in a hot tune with these old trucks..

Ok, I noticed today that I roll coal even with my chip completely out of the truck while towing.
Also I've never gotten a 1211 code. What code is that?

I'm not sure Aaron. I've never checked into it. It's not that I'm unhappy, I love my truck as is, it just bothers me when I can put that 1211 up too easily in my hot tune. Maybe someday I'll look into that.

If you set it to stock before removal, it shouldn't be smoking at all.
Maybe you have a boost leak.
Joey builds good pumps, but there's better ones out there. And at least you can get ahold of the builders also, which is a big thing in my book.
I've seen people trying to contact him for 3 or 4 months, still no answer.
Yeah, other people sell his pumps too, but sometimes you just gotta have answers straight from the horses mouth.

I havent been able to get a test run in again, I will soon.
So someone please explain the pump psi parameters and the DC percentage parameters.
Also a couple questions.
Where should I be psi/DC wise without a chip?
Also is it that the more oil pressure the more fuel it can move through the injectors, or the more times it can open the injector per second?
How exactly does it work?
Is higher pressure good or bad?
