Low EGTs at idle and driving

This is about the truck in my sig. I just finally got around to installing EGT, fuel pres and boost gauges today..

I think it's important to note I'm running TSD's Mild Panty Dropper with open vanes at idle. And I have a 6 speed, not sure if y'alls autos put some load on the engine at idle...So she only idles at about 180-200*F, and I don't have to wait for her to cool down after parking cause EGTs drop FAST on decel and are already about 250* when I stop. On the highway at 60-65 I'm seeing about 550-570* on fairly level ground..Probe is located in the manifold in the usual spot, just before the bend to the up-pipe and behind the last cylinder.

Am I just lucky? Still have the factory downpipe with resonator, 4" open after that. My boost still right on, and I can still build 28psi at WOT.

I have mine in the same location and I idle at about 300-320, I DO have to wait for it to cool-down to kill it. I have a lot more performance mods than you do so I dunno. When I was still stock just with EGT and Insight I don't remember seeing it that low though.

Back before my FICM had PHP's Atlas 80 and I still had stock sticks I would run about the same as you @ 65 on level ground though.

I'll also throw in that she idles around 750rpms w/590 ICP. Not sure if it's relevent, but thought I'd read of others idling down in the 600rpm range

Well less fuel = less heat & more fuel = more heat. If you decide to get new injectors I would highly recommend Warren Diesel injectors. They are fairly cheap and you will not find a better person or better customer service than Jesse Warren.

I already stated that concept. Perhaps you missed the placement of the question mark.

Any confirmation of it possibly being bad injectors, ways to test? Or other reasons for low EGTs or if it's really bad at all...I mean the truck runs great, plenty of power.

your truck could totaly be different but for me that is what it turned out being. I hand a poor injector that ECm was adding all in could trim wise and lowering the other trims to smooth out the running and since it was still within spec I didn't get a dtc. Now it was starting to get worse so over time I would have seen a dtc. I just hate waiting on things to go wrong so I started replacing injectors. What I did notice is if I was in park truck running and held the rpms to 1800-2000 the motor didn't sound even like it was firing some good and some not so good. Now if I do the same it sounds even and smooth. Question though was was the out side temp when you saw the egts as this does play a role
