Don't count in the SCT showing accurate reading for EBP. I remember seeing this before. Jr Anthony should get Forscan or another device to verify it before going crazy thinking something is wrong.

ICP Idle percentages at Idle???
[I am curious what my ICP duty cycle percentage should be at Idle currently I am at 0.14 but sometimes it could be in the low 20s but not to often is 0.14 kinda low? If so why possibly I been reading and .22 to .24 is what I am seeing as a common any input would help I currently run a SCT Livewire TS+ with Stock options for the performance mode I have running issues misses alot while accelerating I have New ICP IPR New Glow plugs and Controller New premium Injectors blue spring and soon as I get home a new EGR and new Mah Sensor as well as New Map Sensor any Suggestions, Soon I want to get a tune written and downloaded just can't afford currently but will in a couple weeks? I need some Direction or Info Please and Thankyou Coop
QUOTE=87crewdually;15181069]I'm assuming you are talking about IPR duty cycle % at idle, not ICP pressure. 21% is rule of thumb for me. If you see it getting higher at idle, say 35%, then more than likely the system is developing a leak.
23% is no worry.[/QUOTE]

Monitor and check your ICP, ICP desired, ICPvoltage, & IPR% values @ KOEO. Start the truck and then check them again. Your ICPv should be ~.18-.23v KOEO and go up from there, based on pressure.
