Running great, but rich at idle....
How do I lean out the tune for idle only? Overall, my 383 is finally running great and very driveable. Gas mileage improved and all sorts of things are just better after my dyno tune,
But when idling, it's rich to the point of eye burning when standing behind the car. I have TunerCat and a decent understanding of what's going on in the PCM, so I will make the changes myself. Just looking for the voice of experience on what's my best bet for leaning the A/F ratio at idle without affecting the rest of the RPM range?
