I have came in late in the game obviously. If you have 80lb injectors and running them at 20psi, you have approximately 100lb per injector and you may have a little too much injector. You can try to lowering the minimum BPW times under BPW Limits. I don't know how much it will help you. I am running 61lb/h injectors at 27psi currently and idle fueling seems ok. Can you lower your fuel pressure? If so, you may have an easier time tuning this thing. Another thing I noticed is not a lot of spark advance at cruise. How heavy is this vehicle? I'll look at your bin this evening when I come back in.
