6nz c15 weird on going high EGT issue, unloaded

I'm just guessing now, did you check fuel pressure ? Or air intake restriction ? Is the cac and a/c condenser and radiator fins plugged with dirt ?

 

Mine runs around 900 to 1050 in summer. But normal for the way I have mine setup.

 

Mines set at 475, and in a dump truck . About the only time I can work it hard is hauling over Teton Pass, which is a 10% grade. Also, despite conventional wisdom, I don't pull it hard below 1500 rpm for long. About to crest a hill I'll let it pull down to 1200, but on a long pull I just go ahead and downshift. Call me old fashioned, but it just seems easier on everything to me.

 

Is it a aftermarket cac ? And aftermarket a/c condenser ? I know certain aftermarket a/c cond. Restrict air flow from their poor design.

 

Yep I usally grab one at 1500 also, but as you know I push a little bit more ponies !

 

If I read correctly you have a modified program in it. Maybe the stock turbo isn't enough. I don't like to tell you to do this but take a zip tie and kink the little hose that goes to the waste gate and run it a trip and see if that cools it down, but don't leave it like that you can over spin your turbo and damage it after prolonged use.

 

The rag thing is only if you have blockage. It isn't really a fool prof way of checking.
