..... I was just
commenting to John that I have never seen RAM recommend any particular
EGT,
only the 1650 degree max. I agree with the rest of your post.

I don't have RAM's newest engines, but their power charts for the RAM
Series II and RAM Series IV TSIO-520NBs had columns showing EGT's.
Typical row entries are "Takeoff (full rich) - 1450F to 1550F",
"Cruise Climb (85%) - 1450F Calibration Setting",
three different types of "Cruise - 1550F" entries,
"Normal Descent - 1300F min, 1400F ideal", and
"Approach and Landing - 1200F min, 1300 ideal".

You may want to call their customer service and get an updated power card.
The one I have justs shows "1650 degrees maximum" for the cruise entries.
They are letting you determine what you want to run at. I think you are
operating them in the proper way limiting the EGT to 1525 or lower.
