What is common crusing egts for a 95 with 370s #6 and a scotty? My pryo dosen't even move unless I hit a hill or stomp on it, the hottest I have seen it is about 800. Just making sure this is about normal, I just bought the truck with these mods done. Thanks Heath

I would say you have a problem unless your gauge starts its readings above 500 and your probe is after the turbo elbow. My probe is pre-turbo and runs in the 425-550 range when empty and level running around 60 mph. See my signature.

Sounds like the thermocouple is too far back from turbo or it wasn't installed deep enough into the pipe.

Sorry, my thermocouple is pre turbo, right in the center of the exhaust manifold.

Hope your probe isn't right in the center, there is web there, the probe would be into soild steel.
Something's wrong though, you should be able to hit at least 1000 even stock if you stomp on it. Take the connections apart, usually about a foot from the themocouple, and make sure they're clean.
Sometimes if the compression nut that holds the probe in place is overtightened it will damage the themocouple and cause it to read wrong.

Mine is pre turbo and it runs 550-650 at 55-65mph and just look at the gas pedal and it goes up. Thats with a #4 plate 4" exhaust and stock inj+turbo

Well I checked all the connections and they seemed fine. I lossened the top nut on the thermocupler and the probe is stuck, can't move it, tried to twist it to, won't budge. Then on the drive home it doesn't work at all now. I don't know what to do now.

Replace the thermocouple, they are available separately.
Make sure you have a replacement before removing the old one as you will likely destroy it while removing.

The pre-turbo probes are usually centered in the back half. Take note to what Infidel said about your probe location.

If you destroy the probe while removing it you will have lots of debris in your manifold... pre turbo. This can kill your turbo. Even if you don't see any visible damage to the probe it's possible that some metal from the manifold chipped off while you wrenched on it.
