Was doing some research yesterday evening as I try to do on these trucks and realized that I put my EGT probe in the wrong spot. I installed it post turbo and from what I read last night they need to pre turbo to get an accurate reading. I researched this before I order my gauges as I've done before and I have no idea how I missed it. I know some can go post turbo but I want an accurate reading. I don't think I have gotten to hot seeing as how I only touch 1000* once before (hadn't towed heavy with it yet and I don't have a programmer.) I read somewhere that running it post turbo you lose about 300* on your gauge. If that's true I prolly wont be in a rush to change it but if it aint I need to do it pretty quickly. Normally I run about 300*-400* idle and riding at 60 mph may 600*-700*.

55 MPH I float 2-3 PSI of boost and 400-600*F EGT's.Idling I can pull as low as 250*F but typically see 300*F.Towing 8K travel trailer with Edge Comp wide open. No problem 700-900*F roughly on flat ground. But climbing a grade no problem either 1,100*F in 4th gear on 6% grade at 53 MPH.

I don't have a trailer, but my numbers are the same as Mikes, only my idle tends to stay closer to 250 than 300.

Same as Mikes, 55 is typically around 400's on level ground. I do idle more in the 250 range.

Just plug it with one of these and have it tack welded (if you need for piece of mind) http://secure.chassisshop.com/partdetail/993301/ Then retap the manifold carefully with a tap piece and some grease ......... and your good to go. No problems after turbo - you just have less of a reference point (from other members knowing what temps you should be running) and your also further from the exhaust with a turbine inbetween .......... so some say less accurate

I drilled mine post turbo as well. I ran this way for about a week and I couldn't get it above 1100*.

As you can see from this picture, I used a pipe plug and a partial piece of a union that I cut off for a locking ring.

And this is where I relocated it too.

Your egt's seem high for post turbo and a stock motor, maybe a boost leak? Mine was post turbo when I bought the truck but I put a copper plug from home depot in it and drilled in the manifold. I have since got another down pipe piece and now no more hole.

350-400 idle, 600-800 driving around, 1000 pulling hard, 1200 flat out for long periods at 40psi.

and as far as idle goes it dependes on the air temp and humdity..watch your gauge and record at different temps in the summer..and then in the winter watch them and record them.

The issue with a post-turbo probe is the variance from a pre-turbo probe varies. It may be 0° at idle (cooled down), or 400° towing, and anywhere in-between depending on exhaust flow and workload. So the 700° you saw cruising may have been 750-800° pre-turbo and not bad, but the 1000° could have been anywhere from 1250-1400° and could be bad.

Well I just made a run down to Payette TVM hauling 6,200# of scrap metal. My EGT's on this trip ran about 600-800*F. Then climbing over Midvale Grade (6% grade) I dropped into 4th Gear held it at 55 MPH over the top and it hovered right at 1,100*F the whole way over the grade. Barely got to 205*F worth of coolant temp.

Remember:

Edge Comp set to Kill (5x5)

RV275 Injectors

Stock HX35W Turbo

Straight Pipe 3" Exhaust

BHAF

Wonderful to arrive at Payette, ID TVM and see 14.2 MPG... (Bonus)

Heck I do that every day at 11245lbs and getting 15.75 mpg with no electronic help

But your without a trailer. Right? ...so Grosss Combined weight for me would of been roughly 14,000 pounds between truck and trailer.

Gota poke at ya

Sorry hadn't been on over the weekend worked a lot. My numbers were slightly less today than what I posted earlier. It was probably 8-10* cooler than normal. I do think I will be moving it up to Pre-turbo to get an accurate reading.
