So I'm not able to run my engine much beyond 15gph LOP at high altitude without exceeding 1650 on my right turbo.

I'm trying to figure out if I have a gauge problem.

 

What spread do people see between egt and tit? 

 

What spread between the left TIT and the right TIT?

 

Mine is about 100 dF.  Since there are 6 egt gauges I'm inclined to believe that not all 6 are broken the same way.

....whereas the tit may be suspect.

Also, my right TIT is 50 dF hotter than the left.
