Did you shorten the leads form the thermocouple? They are designed to read the difference in amperage in the bimetal strip at the tip in milliamps. The leads have a specific length the gauges are calibrated to. If the length is changed, they will never read acuarately. Just a thought. Some guys shorten them to avoid having all that loose wire hanging around. It may be just a short or loose connection like dieselrod says too.
All connections good and tight, and did not shorten anything. Thanks for the ideas.

Thats one of the things that made my get the optix gauges over the isspros. I melted the thermocouple wiring on the exhaust manifold once and it made my pyro flick back and forth and kept locking the door locks on me 
.
Hope you get it straightened out

Just a note to those of you who where talking high temps and watching the turbo. Pyrometers are to monitor exhaust temps to protect pistons not the turbo. The exhaust side for the turbo can take nearly twice the heat the pistons can.

New amp box did the trick!! Jumps up immediately to 250 at start up and went as high as 1150 floored on the highway. Then cooled down to about 350 after sitting for a few minutes before shutting it off. Seems to work perfect now.
Now for that pesky boost gauge....
