O2 Running Rich

[vld]

Datalog on the Diablo reads better than .8 on all o2 sensors (.9= rich). how can i lean this out? already have timing maxed and wot fuel trim leaned to max.

If you are trying to determine your a/f at WOT, you are wasting your time without a wideband.

please... before you blow it up pull the timing back and add some fuel... as jstreet said.... you NEEEEEEED a wideband to tune for WOT...t he stock narrowbands are useless for tuning.
