I have the following done/bombed on my truck: EZ on 4, 5" exhuast and a Intake. I just installed an EGT gauge (DiPricol) and set out to see what the EGT's are. Now all this testing was done unloaded. Thing is, I read about others getting very high EGTs and I can't get above 900! BTW, probe is PRE-turbo and installed by a diesel mechanic.

idle: 200
idle after warmed up and pulling up to the house after trip: 300
normal highway cruising 70mph flat road: 400~500
Full throttle 0~70mph: 900
Full throttle 50~80mph up slight hill: 900

The truck pulls read good, much harder than stock for sure. Made my Ford buddy jealous I just think these EGT reading are kinda funny and was just curious since I have read that some people can hit 1300* on an '03 and no matter how hard I try the highest I can get is 900. Is there something wrong? maybe a bad EGT probe? I just want to make sure that the gauge and probe are working correctly and I am not actually hitting 1400* If all is normal then I need to find a way to get more fuel in there :P

 

Don't own a 03, but have installed EZ and Gauges in quite a few. You mentioned a 5" and intake. I think that is the difference between 900deg and 1200deg. Even without the exhaust change on the 03 the intake makes a large temp difference. I would say your pyro is working fine. I will also add that I have had trouble with the only set of DiPricols I installed and do not use them anymore, but I think yours is correct.

 

i have the x-monitor and my readings are about the same, i too have wondered about the others getting higher, who knows why, i don't.

 

You have about the exact same reading that I do, which makes me feel a bit better about mine. When I pull at 30,000 gcvw I can get it to 1100 and the most I have ever got was 1220 deg. That was really romping on it full throttle through the gears up an on ramp just to see how high I could get it. Like you I read of others with all the high EGT temp problems. Rod is sending me a verified EGT guage to check mine against, will let everyone know the results when I get it.

 

I have a 2003 2500 HO automatic. I have an X-Monitor on mine installed post turbo. I have 3.73 gears with 325/65R-18 tires, X-Intake, 4" exhaust and a TwoPro set on the hottest level. My normal EGT's are right around 300-350 at idle, normal driving 4000-525, a run at 2500 rpm with the cruise locked at 100 mph(3-4% uphill grade) 575-650. My max hot rod EGT according to the memory on the montor is 743. I'm ready for some injectors next.

 

Nice to know that everything is normal, or atleast a few others have the same results <br><br>Gonna do some reading and look into futher modifications. Injectors and a bigger turbo will most likely be the next upgrade for me These diesel bombs are addicting!<br><br>Also, with my setup and EGT's I am hitting 35~37psi of boost. I have read that that is the limit for the turbo... or atleast the point to where its just superheating the air. You guys seeing this level of boost as well? <br><br>Thanks for the feedback

 

Yes same boost
