DTS turbo in 80 1HZ engine

Thanks for useful info. Trouble is mine doing only 3psi @ reasonably high RPM (have not tested it exactelly, but it is high) and I just service it. Because engine doing very well, I plan to go 5, max 6 psi. So how I can adjust it? And sorry my stupidity, but what is EGT guage? My best guess is that it is a termoguage fited in exaust pipe imediatelly after turbo. And BTW I do have hole there.

Exhaust Gas Temperature, measured by a pyrometer or some such thing.

I put a DTS system on an 80 Series that haddone 250k klms I did another 100k before I sold it. Transformed the 1HZ motor. The only problem I had was it cracked an engine pipe but that was an installation fault. They are cheap too TJM were selling them for $2600. Cheers Rob

Quite interesting. Everybody said 8-10 psi max and 12 psi will kill engine in no time. How often do you change oil?

I change the oil and filter every 5000km's, But I've done that with every diesel I've owned.

I rarely need to go to 15psi, mainly when I get to 10psi on the gauge I decied if I need to go any higher and use the right foot to keep the boost at around the 10psi range.
I don't know if the intercooler makes much difference as I have never ahd the cruiser without it.
I do now some people who run 18psi and over in comps rigs and these engines also seem to last if they are cared for properly
