I just recently had an extensive annual done and while it was being done we installed new GAMI injectors.
since the annual the #4 cyc (middle pilot side) is getting hotter than previously indicated. it leans out and cruises around 415 where as it used to top out around 390.
all the other cyc are 340-380, as expected and seen previously.

any idea as to why?

the mechanic changed probes around. still same effect.
we did add new baffles flaps around the engine but i would have thought would have improved airflow.
there doesnt look to be anything blocking airflow either.
