Koso dual egt gauge

[carms]

New turbo installed on a brAndnew pro with koso egt gauge. The temps once installed were equal in each cylinder at first start up. After that one cylinder reads proper temp and the other is around 800 deg off. I don't think I should have problems with the probes already unless faulty probe, has anyone had problems with these gauges?

I have seen about 180 difference between cylinders when coming up from ambient but then they stabilize equal. 800 degree variance in my opinion would equate to a very noticeable if not audible performance imbalance. So if you do not notice that, I would have to bet you are seeing probe failure. Switch the leads from channel A to B and vice versus and see if the problem follows the probe. That will tell you for sure. You could also infra red guage the y pipe at each probe location and compare those temps also. They will not be the same as probe tip temps but should be equal to each other across each location unless you truely have a temp discrepancy as the guage is indicating.

Definately no performance difference, i figured it was a faulty probe just cant believe its like that prior to one ride even. I will switch the leads and go from there! Thank you for the info i appreciate it!
