The AFE could definitely be a problem, especially if it skews the flow of air hitting the MAF sensor.

On top of that, are you sure all your pre-cat O2 sensors are working properly or plugged in correctly?

There have been quite a few E46 M3 guys installing headers recently. Not pulling any codes, hop on the dyno either with or without a tune, only to be disappointed and finding out they are running very rich. End results, ends up being mixed up O2 sensors or damaged one.

It is definitely worth looking at. Best of luck. In either case, Evolve will help you out until you are happy.
