Question Help with monitiring ICP IPR and pressure.....

So my 03 EX is getting the ICP pigtail and IPR replaced now. Currently we are a still a little iffy on weather the HPOP is performing as its suppose to or not. Once the dealer is done with it I want to monitor the ICP IPR and pressure on my insight but I need to know what values I should expect. Can anyone shed some light on this for me? Thanks!

Lots of search info on it. Need 500 psi to start. It idles about 600ish. Most normal systems reach 1500psi during a longer crank. The IPR will be at 15% before start and then start to close to build pressure. If it goes over 50% during a start you might have a leak. On a stock tune you will see 850psi to 1000psi at low load at highway speeds withe the IPR about 25%. At WOT you can expect 3500-4000psi and IPR 75-85% under load.
