The Service Engine Soon (SES) light was caused by a Lean Bank 1 issue. That explains the wandering idle and rough light load at low rpm. As soon as I push the throttle the engine seems happy again and at speeds above 45 mph she seems to be fine. I'm thinking that the fuel map is off on the low rpm side. Cruise at 60 mph and above is fine.

The AFR gauge is going in tomorrow night so that may help understand what the issue is. I am a little confused about why the idle would be so lean. That part of the map should be virtually stock except that it needs to be leaned out because of the larger injectors. Fuel pressure is running in the mid 50s so it has plenty to work with. Anyone else seen this problem?

I did try both tunes that Stillen provided and they run about the same at idle. I have NOT gone above 3K rpm and all of that has been with very little throttle input. I'm babying her.
