What should HPOP pressure be?

I put my scanguage in my truck today and set the x-gauge up and HPOP pressure is at idle 500psi and wot it sees 2800psi. The gauge only checks every 2 seconds or so so its not like you can see the whole movement. But its holding 2800psi at 14lbs boost.

Will the hpop pressure fall when you run a different tune. This reading was stock. I did not see what the duty cycle was either. What should the duty cycle be?

Well seems to not tow well kind of lack of power. I loaded the 60hp tune today and I could only hold 2400psi. I called beans and they want me to check what the duty cycle is and pressure. So I am going to check this out tomorrow.

Every two seconds? That's awfully slow.

The higher the HP program(longer injector pulse width), the more you will see your max psi drop.
