HPOP Tech Help Please

I installed a Termy T-500 and still seem to be running out of oil.
My ICP peaks at 3000 psi then starts dropping off while the DC continues to climp to 75% when I let off.

I have not figured out the data logging yet so can't post those.

If someone has a idea, I can be reached here or at 406-939-0177.

Did you use your old IPR. Did you use new IPR o-rings?

I used a new IPR. Injectors are stock.

Could this be an oring issue? ICP and duty cycle look good at idle.

Honestly man, it sounds like stock injectors. Stack AD code injectors are oil hungry SOBs. With my modded 17*, I was only able to hold 2200psi ICP with my stock injectors. Same HPOP with Stage I SS, I hold 3100psi ICP all the way up to speeds I can't discuss in a public forum.

Also, on stock injectors, the duty cycle would continue to climb and the ICP would not. I don't think the numbers you are seeing are too out of line for stock injectors.

I'm wondering if this is the problem I'm having on my trucks after the T500 install. One is acting really weird, and the other one is a bit noisier too.

It does take quite a while to get the air out of the system, like 50 miles or so. My truck runs really good. I'm just learning what the twin pumps are for.
