Finally got all my gauges installed. What is the acceptable range for the Pyro? It is an ISSPRO? I will be towing this weekend and just wanted to get an idea of what to expect.

If you have the probe post turbo I think it's 950 and if you have it preturbo it's 1250.

I installed it pre-turbo... Is 1250 normal, or is that cooking the engine hot?

1,250* is max! I've heard no more then 1,250* for 30 seconds.Bone stock, (muffled exhaust, stock intake) on a slight incline cruising at 60, about 2,000, maybe 2,100 on the tachometer, pulling 8,000 lbs, I saw 950* for a few seconds, and then I topped the hill, and they fell back to ~700*. :thumbup2:EDIT: After I put the BHAF on, I pulled the same hill with the same weight, and EGT's were about ~50* cooler.

Texas CTD - Thanks a bunch. I pull about the same weight as you, and our trucks are about the same. You must have a 4:10 gear, mine is a 3.54, so expect for and difference altitude might make I should be almost the same.

I've been known to touch 1,400*F but rarely and only for 10 seconds or less.My typical limit is 1,200*F and if so then I gear down 1 gear and kick the RPM's back up to 2K and hold and watch the EGT's. Most grades I can pull in 4th gear and hover about 1,000 to 1,100*F in EGT's.

No sir - 3.54, NV4500.

My buddy and I were discussing this exact thing last night. He tows a lot and heavy, as well as runs a 12V pulling truck. Pulling truck is stupid mean, and tow rig is a modified, twin turbo 24v (both are 2gens.)

He runs 16-1800* in his pulling truck. Towing, he regularly sees 14-1500*F pulling long grades, no issues thusfar.

Is this a good practice for the average Joe? Doubtful. I asked about the 12-1300*F range under load for a minute or two, and he responded "wouldn't worry about it"..

Food for thought..

There is another factor most miss. How about the accuracy of the pyrometer gauge itself. Also the location of the probe either post turbo, pre-turbo 1-3, or preturbo 4-6... all play a role in the EGT's and measurements.

1250° is considered the max continuous for most motors and normal timing settings.

i have my edge set to defuel @1300f i can easily get it there if i want, but try not to. normally i sit round 700-850 cruising no load

I just noticed your sig... How did you 01 have a DPF?

What's DPF?

Diesel Particulate Filter http://en.wikipedia.org/wiki/Diesel_particulate_filter

I must be confused, or I am the wrong guy replying to this thread... I don't have a DPF, and I don't recall ever saying I did.... This is Utah Dully...

Sorry, I was talking to CUMMINSDIESELPWR.

He was reading the signature of CUMMINSDIESELPWR , look at his sig from post #11 above, says he has the dpf "Diesel particulate filter" deleted which didn't come along until around 2008. Nothing to do with you.

While towing with my 02, I ran 1250-1300 consistantly for years with no issues. Measured Pre-turbo rear section of manifold collector.

I know guys with modded 3rd gens who never see anything less than 1200 while towing full time.

CUMMINSDIESELPWR, not Dieselautopower

you're confusing me, now.. but that's easy to do, as of late..

Fixed it lol, reading one thing and thinking another.........Happens a lot more since I broke 40 a couple years ago.

Wait till you are 60. I cant remember to zip up my zipper anymore:doh:. No wait that happened at 50, now I cant remember what happened at 60. If I remember Ill let yall know.

i guess it was a dpf. it wasnt a cat i know that.
