I have my pyro mounted pre turbo in a 2001 with a high output.
I pull a trailer that is 11,500 up a 6% grade for 6-7 mi. My pyro reads about 1350°. is this normal for a stock truck?

It sounds alittle above normal, but the temp is WAY to high for that long of stretch. You can do some turbo damage if you do it for a long period of time. You should consider a larger exhaust system and a better air flow box, like a Scotty 2 or a BHAF to let that turbo breath. Just my $.02.

 

Long, steep hill with a fairly heavy load...Sounds possibly about right. Also, way to hot to stay on the throttle for that long a time, IMHO!
What Gear/Speed? Did you try others?
I'm sure others with more towing expirience than I will chime in here, but that's hotter than I would be comfortable with.

 

that is 4th gear pined to the floor

 

owtlaw i have to think you are getting to hot. i did my exhaust and intake before the gauge install. i wish the gauges went in first. i do belive that a good intake and exhaust will bring the temps down.

 

I took my EZ off for a trip once and that's exactly where my temp went to. Now with the EZ on and the turnbuckle installed I can't get it past 1150.

 

is anyone else seeing these kinds of temps?

 

Towing our 13,500 lb 5th wheel, we're seeing the following max EGT's on 6-7% grades:

Stock - 1300 degF @ 21 PSIG boost

EZ, 4" exhaust, BHAF, stock injectors - 1100 degF @ 30 PSIG boost

EZ, 4" exhaust, BHAF, DD2 injectors - 1250 degF @ 34 PSIG boost

EZ unplugged, 4" exhaust, BHAF, DD2 injectors - 1100 degF @ 30 PSIG boost

I'll second Sandman's post. I could reach those temps pretty easily before the EZ, Scotty II and turnbuckle. Now, I can't get past 1150 and have much more usable power.

 

Thats too hot for my taste too but you wont do any turbo damage. You would melt a piston before you hurt anything else. I have read that the Cummins can run at high temps for ever but most dont like to see to high of EGT's (for long periods) since it may take its toll on internal parts. If you think your gauge is inacurate then have it checked somehow. Could be your thermocoupler is wearing out? I dont know, you might want to call whoever made your gauge.
