So here's my pucker moment for the weekend.
My pyro has been acting up lately and I haven't had a chance to track down what's the problem. It will sometimes hang right at 500* from the moment you turn the key on. After driving for a bit, it will start working normally. So this weekend, I was in Giddings and had to move some cattle around on Saturday morning. The pyro worked fine all the way down on Friday night and running around Saturday morning after I picked up the trailer. So I leave the house with the first load (7 cows, 7 calves in a 32' gooseneck) and of course it decides to hang at 500*. Of course this has to be on the load where I have to run up our steepest hill that has a turn right at the bottom. Figure it's not that big of a deal, I'll just go easy on it and based on past experience I figure EGTs should be tolerable.
Halfway up the hill (just before the steep part), right after shifting into 4th and bringing the boost up, the pyro swings around from 500* and pegs past 1600*.
I figure there is no way I could be that hot already, but still ease up slightly for safety. I top the hill and start down the backside and it's still past 1600*. I keep going down the backside and it stays way longer than it should. Then it suddenly swings back around to 500* and stays there. It started working normally after I made it past all the hill....perfect timing.
I'm guessing I was at no more than about 1300-1350* based on past experience. But it is a little scary to see it peg past 1600 and stay there for about 20 seconds.
I guess it was just telling me that I need to get off my butt and fix it.

Justin, i am new to the mech pyro gauge world and mine seems to peg out at 1500* very fast. (with the edge monitor it would take some work to get it to 1500) i am going to try and put the old pyro thermo couple in and see what this does.

I've ran a couple of loads of 17 bales in the current setup. I was only running county roads, so speed never got over 40. Definitely wouldn't have wanted to make a highway trip, but it pulled like a tractor in the low speeds.
The twins are needed, but the head work is needed first. And time/money is needed for that one.

Must be in the air. Sometimes my pyro does not work at start up. When it does, it reads like it always has. I've jiggled the wires and thermo, but haven't found the problem yet.

Charlie at 4:42 am??? Still up or can't get back to sleep? 
Interesting conversation. Just had to replace my pyro probe. It's just been on and off too many times. Wires got twisted inside probe and started shorting out.
I blame bad, or earlier, design by ISSPRO. Can't get thermocouple out without removing manifold mount... due to compression washer. Requires twisting lead wire to remove. I installed a 'K' style connecting plug in line to solve problem but damage was already started; finally failed.
I recommend removing them and cleaning carbon off every so often.
I think modern thermocouples last longer than they use to but my new clean probe reads a bit lower than previous one, and cools down much quicker!
