Here is a pic from my recent test flight (post injector tuning):
As you can see, my EGT's are very tight and peak together, but I have a pretty large CHT spread (approx 55 deg) between cylinders 1 (coolest) and 2 (hottest). What gets my attention is the fact that the spread exists during all conditions (idle, climb, ROP, LOP). Would this be an indicator of a separate issue besides baffle? If it was a baffle issue, I would think that the temps would be fairly tight on the ground and then diverge once flying, but that isn't the case. Any ideas?
