1999 7.3 ICP and IPR Values

Good evening guys,

I am new to the 7.3

I bought it with the service engine light on. First I changed IPR and ICP Pigtail and nothing. Today I got around to changing ICP Sensor and finally, the service engine light came off.

I started checking with the torque App the values and it's giving me ICP 729.6 psi and IPR 14.3% at IDLE and HOT. I believe these values are wrong.

Can someone help me please determine what is wrong?

Thank you.

I think icp should be around 500 at idle, that ipr doesn't sound too far out. How's it run?
