You answered your own question.
By going with OEM air cleaner, you REDUCED air flow to the engine.
Therefore you require less fuel
If you replace with stage 1 air filter, you INCREASE air flow, and you will need to compensate by increasing fuel ratio.
My first suggesstion would help you.
Here's another issue:
When HD did the stage one air filter, I assume they re-mapped your ECM for that filter.
Others need to chime in here to see in you're OK with an OEM air cleaner and stage 1 map.
