On a diesel higher combustion temp means faster the fuel will ignite so you would decrease timing. Its fine if you all don't want to give up your secrets on tuning I get that. But if someone calls me on an generic sbc running on the street I can tell them a good place to start on fuel pressure, timing, injector pw to get them started. I understand that diesels are different but I still think there is good starting points out there. Like when you said 12.5kpsi and 14.5kpsi in the cruising region. That is experience with the 5.9 that I am looking for. Some that has a go to when they start setting up one of these
