below desired Continuous and KOER on-demand test IPR valve failed, stuck, or shorted to ground

I get the same code but i have a stock oil pump and stage 2 injectors would that be the same problem or the censor or just low oil pressure

I would replace teh IPR jsut to be sure, other than that your running out of oil volume, and can not hold desired pressure.

If it is just at high RPMs while under hard load, then it is normal. If it is random and comes on without reason then it is the IPR.

ya thats what i thought i never get it randomly it just under a hard load at higher rpms.

only at about 26-28+ lb of boost is it because of the AD's needing more oil than say AA stage 1's? As soon as i get time and a good weekend I have stage 1's AA's going in should that clear it up ?
