I had an issue running rich as well. I've only had the IX in for maybe 5-7k as well and it's been hell. Rough idle, and ran pig rich. The tune was spot on when I had the tr55's though

I am gonna data log individual missfires with my 55IX plugs and grab a set of 55s and see what ones have less missfires.
