Have you looked at the MAF sensor? Just a guess. When I added my CAI and unequal headers & new O2's it read it as lean. So put on an AFPR at 42 psi at idle still was lean. It was the filter oil had become baked on the sensor. Cleaned it with brake cleaner so not to break the little wires on the sensor and the light hasn't came on since. And it runs a ton better.
