Here are few what if's that I'm thinking might help:
Swap the computer chip between the FJ40 / FJ55 and see what happens?
Data log both vehicles with each chip? (I'm thinking the FJ55 should show good data logs with both chips?)

Good ideas!

But I think the rich is from the cam. As RPM increase in log BLM are better, pretty common cam change data log.

It's always a good idea to have injectors serviced before tuning! I always have them done and see as little as 3% to as much as 12% difference, the worst ones are 35 on one side and 12% on the other!
