I turned my fuel up almost 2 flats (about 110 degrees) and that might be too much fuel. I did not notice any great increase in EGT going from 1 flat to almost 2 and I did manage to get up to about 7 lbs boost max.

With the turbo it will handle the extra fule better more fule=more boost to a point wich means the more fule can be burned as eficiently so you'r egts dont rise much. Yes that is what i mean by a flat.
I was saying when you get a pyro and want tuo turn up the fule you should turn it up a flat then drive it and see where your egts are then one more and so on till you get it where you want it. Depending on where your timing is set what injectors you have and what shape they are in you will get a different afect from turning the pump up.
It sounds to me the more i think about it like the the original poster may be lugging his engine causing his EGt to go up.

you also have to remember the OP has a stock truck. no turbo, no oversize injectors.

Turbo's move more air through the cylinders.
Yes that means you can make a bigger fire if you stand on the throttle, but all you have to do is back out some and more air cools things off faster.
Where exactly did you install the thermocouple?
If the thermocouple is in the exhaust manifold, 1000 degrees is an OK temp.
I try to keep mine under 1100 most of the time.

I just got the truck back from the muffler shop. I had the Y cut and replaced and an all new 3” installed with a flowpro. I did not want a lot of sound do to the wife and all.
My EGT readings before the new exhaust where as follows:
490 degrees at 50 mph
510 degrees at 60 mph
580 degrees at 65 mph
These were steady speeds on flat ground with no load in OD with. I will check what the new temps are and post them.

find out what they are if you get on it a little hard from a dead stop up until about 60 mph

I'm still running high EGT's here in the mountains. I ran the truck up hills at 2800-3000 rpm. and as soon as I headed uphill the EGT's started to rise. The truck was empty and had plenty of acceleration. It went right up to 1200. When I get a chance I'm going back the fuel off and try it. If it still gets hot I will increase the boost. I have to get rid of this over heating. The truck does fine on level ground even with a load. I may even back it off the 110 degrees just to see what happens.
I hope Brojon solves his problem, I'll bet its fuel related.

when you got your fuel turned up i remember you saying it was turned up in a different spot then most of us turn it up at, i wonder if that has anything to do with it?
just thinking out loud here lol

I just got the new EGT numbers. I noticed there is about a 100 degree difference with the new exhaust. I was running 490 degrees at 50 mph, with the new exhaust I’m at 390 degrees or less at 50 mph. I ran her up to 70 mph and was at 500 degrees. That’s less then I was getting at 55 mph. The faster I go the more the difference. I think this is do to higher RPM has more air volume and the new system is less restrictive. I can’t wait to try pulling the trailer and see what happens.
