is it normal to have a spread in range like this?
Attachment 7633
BWT, I swapped out the roller rockers for roller tip rockers, knock counts went from 3000 to 30 over a 10 minute run. sometimes more, sometimes less, but overall, knock counts are way lower. Also, the surging is still present under no load conditions, but seems to have improved greatly while driving. Each time I run a log and mess with the fuel table, it seems to get better. I'm just not sure about some of the cells, I have such a large spread, I guess once I get it in the middle it will be ok.
