New Turbo=Higher EGT's?

My turbo crapped out on me on friday so I got a new one. Halfway into the install I noticed that the place I bought it from gave me the 1.00 AR housing instead of the stock one. So it has that and the banks compressor wheel. I was driving down the freeway and my temps were about 900 egts. Why would it be so high???? It runs great but man those egts are high for just cruising. They stay lower longer when I accelerate hard. Any help on this. Im stumped. Oh PS its like 10 degrees when I was driving this morning and my pyrometer was stuck at bottom for about five minutes of running before it jumped to operating temps. Are these related. Bad Gauge maybe?

Something is definately wrong with that gauge. It should start climbing almost immediately

Do you think the thermocouple may be bad? Why would it just stick at the bottom and a split second later go up to where it should be

The smaller housing will create more heat, but will also spool faster. I think your truck stock had a 1.15.

Agreed...

900 degrees though is high for just cruising. Mine are around 400 with the 1.15 housing. Then again our trucks might not be identical... do you have bigger tires/lift kit? Dually? etc... also what chip are you running?

Ok i see your sig now... you have 2" bigger tires then me, which should not equate to double the egt.

How fast are you driving while cruising? If I'm runnin 80mph I'll hit 8-900 IIRC...

I was going about 65. I solved the problem though. As I suspected my isspro gauge sucked. I put my autometer gauge I had and like magic, the problem was gone. I was running 600 at 70 like normal again
