So i was reading the pyro gauge thread the other day and it is very clear that if your not stock than you need this gauge. Apparently I am a lucky sob and haven't killed my truck yet pulling heavy loads without the pyro gauge. I would like to hear stories about how often you actually have to let off the pedal when you realize your dang near in the red zone and how close you monitor it when your pulling. I realize you mountain climbers have to watch it more. I would definitely like to hear from some flatlanders like me.
1. Stock tuning ?
2. Weight and shape of load
3. Grade of road
4. Travel speed
5. How deep your foot is in and in what gear
6. Operating condition of truck
7. Truck gearing change by oversized tires
8. Ambient temps
If any given truck has only a tuner on a HOT tune.. And you do a full throttle launch (even not towing) you'll run into 1300 degrees by the time your up 80 mph
You've likely run that truck well into the danger zone. (Sorry to scare you)
So many variables exist to make any forum feedback anecdotal. With my rig, flat towing with GCVW towing approaching 17k, I can run the "hot" tow tune which is the 80hp tow tune and go as fast as is legal no problem with EGTs around 900. Get into the hills and I have to switch to my heavy tow tune.
Gvwr I'm around 13k, stock and what's been mentioned in my threads, I think I may have a problem. I hit 1200 when pulling a 6% grade, so I'm backing off or grabbing a lower gear(6spd).
. I'm not buying the, if stock, no need to worry about egt's...

Your not "scaring" me at all. I think your trying to make this to complicated. Simply give your certain situation (like timmyboy76), vehicle mods, weight being pulled, and if you are on basically flat ground or pulling some grades.

I purpose a different approach to answering your questions.
Post your modifications, typical towed weight and type of trailer and location. Then someone with a "similar" setup to what you have can post their EGT readings. This not only takes the brunt of the work off the individual replying, but relates your situation to one of their own.
Of course, none of that matters at all if your truck has any boost or exhaust leaks.
As mentioned before, it is too hard to predict what EGT you are seeing in your situation and you have been lucky and shooting in the dark.

OK..
Here's mine..
2003 Ford Ex.. MBRP exhaust . intake, DP tuner on 80T ,Everything else stock. Towing about 6000lbs inclosed 16' trailer..
Living in eastern Ontario towing to Norther Ontario.. There are some hills but certainly no mountains like others might encounter..
110km / 70mph it will run up to 1100 with some smaller hills..
As an example.. If I happen to be merging onto a highway in heavy traffic with my foot in it 3/4 throttle towing the EGT's climb hard and fast..
Stock except AIS intake
6-7% grade.
17,400 lbs.

I had to back out of the throttle on a longer pull to keep egts down. Speed about 35 mph and rpm about 2000 rpms. I'm not sure about the gear, I assume 2nd gear.
My "fix" for this was to remove the red wastegate tube and put it on an intercooler clamp bolt. I still don''t know what the root cause is. It does show that a stock truck can appear fine and still run too hot.
With the WG removed and the boost at at least 20 the truck threw a code with a description indicating that the wastegate control was not working. I cleared the code by mistake before getting a chance to grab the number.
Here's a graph showing a portion of a grade pull where backing off the throttle was required:
...I'm not buying the, if stock, no need to worry about egt's...
Maybe if it had the qualifier "If you are sure the truck is 100% with stock tuning, there is no threat of high EGTs." Unfortunately... after all these years, miles, and changes of ownership - that first part is less and less common.
