Tunes and EGTs

Well I noticed what I think is high EGTs for my tune so I am starting this to compare stock vs. tuned both with factory exhaust as well as 4" turbo back both with and without a Cat.

So far I have stock exhaust data.

Stock-1100 WOT
SRL- 1600+WOT

I just installed my fuel pressure gauge today and we will see what happens. I already have the blue spring mod and idle show 68-70# of pressure. I will see what happens to it on a WOT run with SRL loaded up as soon as the roads dry out.

I will keep this updated with the data I get as I go along for others to learn about.

I will say when I drained some coolant to do my coolant filter it was yellow but really clear, no sediment or anything from the radiator drain.

Just a thought as I was nosing around the truck this afternoon. My hot side boot at the intercooler clearly has oil saturation issues. I am still building 25+ pounds of boost. Could the boot allow boost to leak out through the boot but still build enough to appear normal? I did not know that diesels were backwards on high temps (rich is hot on diesel, lean is hot on gas).

My SRL seems smokey at WOT compared to what I have seen on videos from others on here. It doesn't seem to clear up when on it.

I have not been able to get another WOT run but I do have my fuel pressure gauge hooked up now.

I figure I need to post Boost, fuel pressure, and EGTs. Is ICP good info also? Mine is around 3750 at WOT.

Just looking for what to post for the best ideas on the problem.

So I finally got the exhaust installed. By myself it took about 3 hours to install. I ran it with the cat installed and then installed my test pipe and ran it again. Their was absolutely no difference in EGT between the Cat and the test pipe.

On a WOT run I was hitting 1500ish which is around 100 to 150 less than stock with my tune. My boost is 25-26 and my fuel pressure never went below 54#.

I get a lot of smoke with SRL off the go, then nothing once the turbo lights. I also have a really hard time getting my boost over 22lbs. I never thought to look for a leak anywhere though.

My EGT's hit 1400 real quick when i really get on it. I wont usually let it run over 1200 for more than a few seconds. engines are expensive

In another post, you stated that you have the EGR valve unplugged. This might be why your not getting over 22psi. Under high boost psi, you can actually have the valve blow open if the internal spring in the valve is weak.

That is interesting. I towed my 4000lb travel trailer to tofino last weekend. Had to go over a couple small mountain ranges so I took SRL off and went back to stock.

Truck hit 27-29 lbs of boost going up most of the big hills. This makes me inclined to believe it is the tune not my truck limiting boost

Elevation has a lot to do with EGT's. It's common for us Coloradans to push 1600-1700* with the SRL. I do get a bit of haze, and prefer it that way. Think of it this way, if I'm hazing (not rolling coal), my injectors are not starving for fuel
