I am kind of new here but my dad is a truck driver and i have been around diesels all my life, i think a good rule of thumb is no more than 1200 on the pyro. and anything more than 30psi on the boost you probly should have some aftermarket stuff on the engine to take it, it may stand up to 35psi for a short time but i wouldnt hold it there. the egt number changes depending on where your probe is "pre" or "post" turbo too im not sure how much though. im sure one of the experts on here will correct me where im wrong

30 psi and 1200* are pretty good places to set your warnings. Although damage isn't occurring at that point, it will at least draw your eyes to the gauge so you're paying attention and can get your foot out of it before something lets go.

I testdrive the truck today and it seems like the EGT teps stay normal cruising
40-55mph about 600-700

when push the pedal to the floor and make spaad 0 to 75mph it rises 1200 or litle over.
i got SCT-street file in.

all this with no load.

the cruising temps is not accurate cause the trip was 15 miles only, up and down hills no flat land in my way to home...

well in time i got better picture where temps goes, when i get more miles driven.

I try one of my custom tune first, but could not drive the truck with that!
Horrible kill strokes to automatic transmission and evrything else on the truck.

I try to drive as smooth as you can but the transmission didn't know what to do it shift back and forth couple of times then let the rpms rise too high an then, BANG there is the gear!...

i think there is somethin wrong with this tune..

the pre-load street tune and stock it shifts ok.

haven't had time to try others yet.
