I have been trying to nail down a poor idle issue for a while, can someone review my log please. the thing shakes like it has a miss. only seems to be an issue at idle. just installed new 02 sensor and AEM inline wideband. Any help would be greatly appreciated.
I noticed that with the wideband IAC counts are no longer displayed, is this normal? or do I have a setting messed up? What should vacuum be with 206 roller cam?

Looks lean. Verify fuel pressure. 42-45 line off.

Turn base knob to 1 in the translator. That will add 10% to the base tune.
