So if I understand correctly, you installed a supposed performance enhancement product, but it produced error codes.

Without telling us any of that, you asked about another supposed performance enhancement product, in the unspoken hope that it would somehow correct the problems caused by the first aftermarket product?

How were we supposed to make that connection?

So, they put the correct filter back in. Is it OK now?

Computer software can't compensate for vacuum leaks, unmetered air, etc. And buying a product that advertises that it will add more fuel isn't going to fix your first problem.

You would get more assistance if you checked your attitude at the door, IMO.
