It does make sense this rigs previous owner drove it stock and i increased the fuel being injected by not limiting the throttle position, the previous owner could keep his foot on the floor all day and it would never get hot, but I don't get on to freeways going 35 miles an hour, this rig is a 1990 with a cat 3208 v-8 and no intercooler so it does runs on hot air injected by the turbo, my question was did ?I install the egt probe to close to the pistons and valve train?, I added the egt gage to monitor the engine and not melt pistons when i increased the fuel to the engine. Thanks

I have installed several myself with no problems, i was a machinest for 40 years, My question was not how to do it but did i install it too close to the actual piston and valve train, my temps are really high, like 1350degrees or more when climbing, this rig has no intercooler and I don't want meted pistons, but if i installed it in the wrong place my readings could be nothing to worry about, if i plug the existing hole with a 1/4" pipe plug and move it back to just before the turbo which is about 30 inches from the piston instead of 4" will I see temps more like my dodge ram when pulling which is about 1150f.

Call Cat and ask them where to put the temp probe. HAVE your motor number and frame type. They can tell you.

To clarify, AFTER the turbo charger, probe in the exhaust pipe 6" past the flange. If you can plumb up a cac, fuel can be turned up to supply 15#s of boost, other wise, with out cac you should keep the fuel limited to egt's readings of 1000 degrees max on a hard climb. Been there, done that and got to replace head gaskets.
