I experience a mismatch between the "Total Fuel Flow Indicator" and the individual values from each engine. The total FF is indicated too low.

The FO's instruments are bound to Nav 1 only, if CS could make them separate like on the 707, this would make some navigational tasks easier and more realistic.

The FO's altimeter pointer doesn't move, only the digits roll up congruently to the Captain's.

The No. 1 engine sometimes has other readings than #2, as Lost in Isaan stated before. I only add this "sometimes" to it as she seems to be in line again at other throttle positions.
As we all know, No. 1 and 2 are coupled, so individual throttle movements can't happen there due to the internal FSX operation (using the eight engines in pairs of two to actually make them fit to the 4 engine model in FSX).
I wonder what causes No. 1 to sometimes go for individual values then.
