H&S EGT's

[LFD132]

I am running the H&S mini maxx on the hot damn tune. What kind of EGT should I see on normal acceleration and driving? Noticed them staying in the 600-700 degree area. Is there something I can do to bring that number down? What kind of numbers do these trucks run stock under normal operation, excluding regen?

That seems like a somewhat normal temp range to be honest, maybe even a little low. You must accelerate pretty dang easy. I was seeing a little higher (800 to 900) than that when i had my 6.4, running the Edge CTS evolution race tuner.

A friend of mine just installed the Spartan Phalanx and ran the truck with the stock exhaust for a few days while running the "DPF ON" tune. He says that during the regen cycle, his EGT's were 1400. I can only take his word as I have not witnessed it personally.

Your numbers sound about right for normal driving. Egts will move around a bit depending on the load on the truck too. Like whether you are going down a hill, up a hill, or level ground. Aftermarket intercoolers would probably be the next thing to look into if you do want to drop egts a little more.

My truck now sits on 38s and 8 inches of lift and going down the high way on h &s 130hp tune in the easy files my egts sit anywhere from 600-750. I like them to stay mid 6s but from what I have been told my truck is running nice and cool.

Thanks for the input guys. I don't usually drive with an overly light right foot, but I wanted to get an idea of where my truck operates for a baseline, and then see if that seemed to be the consensus with everyone else. When you are running in the 700's your about half way to the de-fuel setting. Doesn't leave you a lot of petal before you start to alarm. I don't want to increase my de-fuel setting, I would rather lower my EGT's.

I use the hotdamn tune and see those same kind of numbers, I think its the nature of that big of a tune. H&S mild tunes dont build those temps nearly as fast, the Boost and temps stay relatively tame in comparison.
Im thinking the 4" into 5" turbo back exhaust would help lower those numbers.
With the DPF installed, the temps in the oe downpipe are alot worse, and is the reason for the double walled pipe.
