Running lean after adding dual snorkel

I added a 5.0 HO dual snorkel air cleaner to my LG4, including installing the vacuum lines to the carb.

Since then my check engine light has intermittently come on with code 44 (lean).

Any thoughts why this could happen with the better flowing air cleaner?

You've probably inadvertently created a vacuum leak.
