03 icp issue i think

[tatertot]

Ok guys have a question drove the truck today and playing with the scangauge just before I left the driveway. Noticed my ICP pressure was 580 and IPR was 20. I think that is low I know it needs 500 to start. Drove to work and at lunch started it up jumped to 1500 then 825 within 3 seconds and stayed there till it warmed up. On the way home only could get it up the icp to 1440 and ipr to 32 at 70 down the road.
Recently added the Hybrid and looney tune to it was wondering if the tune could do it or I got a leak somwhere.

Tunes trick the ECM into thinking icp is low, so yes that's most likely your sudden drop.

If it was a dying pump or leak (less likely on an 03), the icp would be real low and the ipr would be real high % trying to get more oil pressure.

portcity is correct this is tuning

If your tuned, your better off reading ICPv and convert the volts to psi. Unless you run DashBoss, which gives you calculated ICP psi based off of ICPv.

There are several threads floating around with the ICPv to ICP psi conversion.
