Hi Paul,
Looking at your screen shot and comparing your cht's and egt's to anything I've ever seen in operating my Sonex, I have a couple of observations. First, regarding your flow straightener.........your egt spread is greater than I would typically see without having a flow straightener. Are you confident your straightener is accomplishing anything? And, second, your cht readings are literally night and day different to anything I've seen in operating my Sonex. Are you confident that you have the cht cylinder numbers assigned properly? Typically, my coolest cylinder is always #1 and the back 2 (5 & 6) tend to be hottest in a climb while the middle 2 (3 & 4) tend to be hottest in cruise.
Hope this helps,
