If the concern you have is hp replated you need to watch the ICP, IPR, and ICP desired pid. You should see within 3 seconds 500 psi of ICP and the IPR duty cycle should go up from 14% to around 40 - 50, its just a vavle that the computer closes off the high pressure oil system to build that 500 psi of ICP needed to start and idle. If you do not have 500 psi of ICP while cranking at least 3 seconds then I would say you have a hp concern. If you do have a hp oil leak you will need the dealer tools or you can fabricate to block off each head and put shop air in the system to narrow down the leak.
