Which car is this in your signature? If it is the car with 120lb injectors, I'm pretty sure Eric sets those particular chips to idle a little higher anyways.
1) Are the switches in your Translator set correctly?
2) What happens when you disconnect the volt booster?...the one wire alternator cable?
3) Have you closed the throttle plate (and readjusted the TPS) to bring the IACs down?
I don't think you really have any problem IMHO and I don't suspect anything is wrong with your MAF. Sounds to me like your AF reading is correct and the high reading is just a natural byproduct of the higher idle. I bet if you go out and flog the car and get it nice and warm it will settle down a bit at idle.
